Short answer: Manasseh's father was Hezekiah, king of Judah. 2 Kings 20:21 says that Hezekiah slept with his fathers and that Manasseh his son reigned in his place, and 2 Kings 21:3 describes the high places Manasseh rebuilt as those which Hezekiah his father had destroyed. The narrator names the father plainly, but the burden of the chapter is what the son did with the inheritance. Manasseh reversed his father's reforms and led Judah into evil deeper than the nations Yahweh had driven out, and that becomes the stated ground of judgment on Jerusalem.
A verdict written over a king's reign
Second Kings 21 opens with the standard royal report: accession, age, length of reign, mother's name, verdict, summary, death, burial, succession. Hezekiah's reign has just closed with a note about his pool and conduit, and the succession formula hands the throne to a twelve-year-old. The shape matters. The narrator frames the reign as a legal evaluation, not a personality profile. A verdict line comes first, then a catalogue of offenses, then a prophetic oracle of judgment, then a closing notice of bloodshed and burial. Reading the chapter as a covenant lawsuit against Judah keeps the details in order and stops us from treating individual verses as detached moral lessons.
The catalogue is deliberately comparative. Manasseh rebuilds the high places his father destroyed, sets up altars for Baal, makes an Asherah, and worships the host of heaven, explicitly following Ahab of Israel. He places altars inside Yahweh's house and the Asherah image in the temple, the place where Yahweh had promised David and Solomon to put his name forever, conditioned on obedience to the law of Moses. The narrator measures Judah against two standards at once: the exodus-era nations and the northern kingdom. Samaria becomes the line and Ahab's house the plummet. The verdict is that Judah was seduced past the nations.
The oracle announces judgment that will make hearers' ears tingle, and the summary adds that innocent blood filled Jerusalem from one end to another. The mention of a son passed through the fire is one of the darkest lines in the chapter, and it should be read with grief rather than as a template for interpreting any family's suffering. This text does not promise that faithful parenting secures a child's faith, nor does it turn specific hardship into direct punishment for specific sin. It shows a king's covenant unfaithfulness, a nation's complicity, and a God who speaks through prophets before judgment falls. The chapter closes in the garden of Uzza, and Amon inherits both throne and verdict.
A Father's reforms undone: reading 2 kings 21:1-18
The passage opens by naming Manasseh's father twice over. 2 Kings 20:21 records that Hezekiah slept with his fathers and that Manasseh his son reigned in his place, and 2 Kings 21:3 then says Manasseh rebuilt the high places which Hezekiah his father had destroyed. The word father works on two levels here. It is family: a son inherits a throne and a memory. It is also royal and covenant: a successor either keeps or reverses the direction of the house before him. Manasseh reverses it deliberately, restoring what his father had torn down. The text states this plainly, without excusing it and without treating the father's faithfulness as a guarantee for the son.
The verdict formula is steady: he did that which was evil in Yahweh's sight (2 Kings 21:2). That is the measuring stick, not public approval or political stability. The specifics matter. High places, altars for Baal, an Asherah, and worship of all the army of the sky describe rival worship with names and objects, not vague irreligion. He built altars inside Yahweh's house and in its two courts, the very place Yahweh had said he would put his name. The passage also records that he made his son pass through the fire. Read that line slowly and with grief; it is one of the darkest sentences in the books of Kings.
Judgment is described as measured, not random. Yahweh speaks through his prophets of a line stretched over Jerusalem and a plummet, the tools of a builder checking a wall, and of wiping a dish and turning it upside down (2 Kings 21:13). The city is examined and then emptied. The stated reason reaches back to the exodus and forward to innocent blood filling Jerusalem. This is not a template for reading every hardship as punishment for a particular sin, and it does not promise that faithful parents secure faithful children. What it does is show a God who sees, measures, and speaks before he acts, and who keeps his word to David even in a house like this.
Manasseh's Father was hezekiah, and the text says so plainly
The answer to the question is not hidden. The previous chapter closes with Hezekiah's death and a note about his pool and conduit, then hands the throne to his son: 2 Kings 20:21 says, "Hezekiah slept with his fathers, and Manasseh his son reigned in his place." The narrator repeats the link when he describes the reign, saying Manasseh rebuilt the high places "which Hezekiah his father had destroyed" (2 Kings 21:3). Manasseh was twelve when he began to reign and ruled fifty-five years in Jerusalem. So the family line is stated twice, once in the succession formula and once in the charge against him. The passage assumes you know whose son he was, because the weight of what follows depends on it.
The burden of the text, though, falls on the reversal rather than the pedigree. Hezekiah had torn down the high places; his son rebuilt them, raised altars to Baal, made an Asherah, and worshiped the whole host of heaven. He put altars inside Yahweh's house and set the carved Asherah image in it, the very house where Yahweh had promised David and Solomon to put his name forever, conditioned on obedience to the law of Moses. The narrator measures him against Ahab in the north and against the nations Yahweh had driven out. Verse 9 says he seduced Judah into evil worse than those nations. A son can undo a father's reforms, and Scripture records it without softening.
That reversal becomes the stated ground of judgment. Yahweh speaks through the prophets: because Manasseh did these abominations and made Judah sin with his idols, disaster is coming that will make the ears of everyone who hears it tingle. The line of Samaria and the plummet of Ahab's house become the measuring tools, and Jerusalem will be wiped like a dish turned upside down. Verse 16 adds innocent blood filling the city from end to end. The mention of a child passed through the fire belongs in that same catalogue of horror, and it should be read with grief, not as a template for blaming any family's suffering on a parent's sin. The chapter ends with burial in the garden of Uzza and Amon reigning in his place, judged by the same formula. The line continues; the covenant betrayal is what the text wants heard.
Where readers differ over manasseh and his Father
Evangelical readers do not dispute the plain answer to the article's question. 2 Kings 21:1 names Manasseh's father by placing him directly after Hezekiah, and 2 Kings 20:21 has already recorded that Hezekiah slept with his fathers and that Manasseh his son reigned in his place. The disagreement lies elsewhere. Chronicles later tells of Manasseh being humbled, praying, and being restored. Some read that as genuine repentance and a real turn; others read it as a pressured king who reformed his policy without a changed heart, since Kings remembers him only as the king whose sin filled Jerusalem with innocent blood. What stays central is that the later account cannot cancel the verdict of this chapter.
A second dispute concerns how the judgment announced here relates to Manasseh's personal guilt. The oracle in 2 Kings 21:11–15 names his abominations and his seduction of Judah, yet it also traces provocation back to the day the fathers came out of Egypt. Some read the sentence on Jerusalem as unconditioned, fixed by the measure of generations of sin; others read it as covenant warning, so that later reform under Josiah could delay but not finally avert it. Notice the image of the line and plummet in 2 Kings 21:13: judgment is measured, not arbitrary. Both readings keep Yahweh just, and both refuse to let the nation hide behind one king's record.
Pastorally, this chapter asks for care. The mention of a son passed through the fire in 2 Kings 21:6 is horror, not a model, and it should never be turned into a lesson that faithful parenting guarantees a child's faith, or that a family's suffering is direct payment for a particular sin. Hezekiah's piety did not produce Manasseh's obedience, and Manasseh's evil was his own. What the text does say is that a king's sin has public consequences, and that grace and judgment both belong to God. The warning stands, and so does the call to humble ourselves before the God who measures justly.
From hezekiah's heir to the greater Son of David
Hezekiah had been the king who made the pool and the conduit and brought water into the city (2 Kings 20:20). His son Manasseh undid the father's work: he rebuilt the high places, raised altars to Baal, and set an Asherah image inside the house God had claimed for his name. A good heritage did not carry the next generation. The text says plainly that Manasseh led Judah to do more evil than the nations God had driven out (2 Kings 21:9). Any parent reading this should feel the honesty of it. Faithfulness in one generation is a gift, not a guarantee, and this chapter will not let us turn a godly father into a promise that a child will follow.
The judgment here is deliberately measured. God says he will stretch over Jerusalem the line of Samaria and the plummet of Ahab's house, the same standards used to condemn the northern kingdom, and he will wipe Jerusalem like a dish wiped and turned upside down (2 Kings 21:13). The image is thorough, not careless. Judgment is not divine temper; it is God holding a city to the same plumb line he has always used. The mention of a son passed through the fire belongs in that same sober context. This passage describes a specific king's crimes and God's response to them. It does not teach that every hardship a family faces is payment for a particular sin, and it should never be used to promise that careful parenting secures a child's faith.
Yet the promise inside the judgment points beyond Manasseh. God had said he would put his name in Jerusalem forever and would not let Israel's feet wander again if they kept his law (2 Kings 21:8). Judah failed, and the house of David kept producing kings like this one. The gospel does not rest on royal lineage but on God's own faithfulness to his word. Where Manasseh shed innocent blood until Jerusalem was full of it (2 Kings 21:16), the city would later see innocent blood shed again, though this text draws no line to that itself. The cross is where the plumb line and the wiped dish find their answer: God's justice and mercy meet in a greater son of David, whose obedience secures a lasting house.
What faithful response looks like when the family line is mixed
Second Kings 21:1–18 sets a father and son side by side and refuses to let either one hide behind the other. Hezekiah had torn down the high places and redirected Jerusalem's water supply, yet his son Manasseh rebuilt what his father destroyed and went further into Baal worship and Asherah images. A godly parent is a gift, not a guarantee. The verdict formula repeats over each king: he did evil in Yahweh's sight. That measure is his word, not the neighborhood, not the surrounding culture, and not the previous generation. Read your own life by that standard before you read anyone else's.
Manasseh's idolatry did not stay private. He set the Asherah image inside the house Yahweh had claimed for his name, and the text says he seduced Judah into evil beyond the nations around them. The passage also records that he made his son pass through the fire, and it names this among his abominations without softening it. Such things deserve grief, not casual reading. The warning is plain: influence runs outward, and the text holds Manasseh responsible for the people he led astray. Take seriously where your own choices, however small, may be teaching someone else to treat evil as normal.
Where you have failed, do not presume on a godly heritage and do not hide behind ancestors. The prophets spoke, judgment was announced, and still the door to mercy stood open in Yahweh's character, though consequences ran their course. Grace is the ground of obedience, not a promise that every consequence disappears. Pray for leaders and households, asking for faithfulness rather than assuming it. And do not use this chapter to claim that faithful parenting guarantees a child's faith, or that any particular suffering is direct punishment for a specific sin.
Biblical fidelity check
The chapter was read as a royal verdict report, not a collection of isolated anecdotes. The risks are specific: flattening the standard formula in 21:2 into a general comment about sin, when the verses that follow name particular practices; treating the reversal of Hezekiah's reforms as mere policy change, when 21:3–7 describes rival worship installed in Yahweh's own house; and reading the judgment speech in 21:10–15 as though it answered only for Manasseh, when 21:15 traces provocation back to the fathers coming out of Egypt.
The real limit is how this chapter sits with the later account of Manasseh's humiliation and restoration, and whether that account describes genuine repentance. Readers also differ over whether the announced judgment is unconditional or a covenant warning that reform could delay. What stays central is that Yahweh judges justly, that a king's sin carries public consequences for a nation, and that neither Hezekiah's piety nor Manasseh's later story cancels the evil recorded here.

Frequently asked questions
Who was Manasseh's father in the Bible?
Manasseh's father was Hezekiah, king of Judah. The text states it at the seam between the two reigns: 2 Kings 20:21 says Hezekiah slept with his fathers and Manasseh his son reigned in his place. 2 Kings 21:1 then gives Manasseh's age and the length of his reign, and 2 Kings 21:3 refers back to Hezekiah as his father when it describes the high places Manasseh rebuilt. The family line is not in doubt anywhere in the passage.
Why did Manasseh reverse the reforms of his father Hezekiah?
The passage never explains Manasseh's motives; it only reports what he did. It lists his actions in order: he rebuilt the high places Hezekiah had destroyed, raised altars for Baal, made an Asherah, worshiped the whole array of the sky, and placed altars inside Yahweh's own house. The comparison drawn is not to his father but to Ahab, the northern king known for importing Baal worship into Israel. What the text emphasizes is the effect on the people rather than the reasons in Manasseh's heart: 2 Kings 21:9 says he led them astray so that they did more evil than the nations Yahweh had destroyed.
Did Manasseh repent, and how does 2 Kings relate to the account in Chronicles?
2 Kings 21 does not record any repentance; it ends with Manasseh's death and burial and moves straight to Amon, who did evil as his father had done. The book of Chronicles tells a longer story, including a period of captivity, a humbling, and a return to Jerusalem, and it is worth reading both accounts side by side rather than flattening one into the other. The difference does not cancel the judgment announced here, which 2 Kings grounds in the blood Manasseh shed and in the people he led into sin. Whatever mercy Manasseh may have found, the chapter's concern is the covenant betrayal and its consequences for Judah.
