Short answer: Manasseh's father was Hezekiah, king of Judah. Second Kings 20:21 closes Hezekiah's reign by saying he slept with his fathers and that Manasseh his son reigned in his place. Second Kings 21:1 then opens Manasseh's reign at age twelve, and 21:3 names Hezekiah directly as his father. The passage answers the question plainly and then sets father and son in sharp contrast.
The throne passes from hezekiah to manasseh
Second Kings 21:1 opens with the standard court formula used for each king of Judah: age at accession, length of reign, capital city, and the mother's name. Manasseh was twelve when he began to reign and reigned fifty-five years in Jerusalem; his mother was Hephzibah. The verse is a formal notice, not a story. Its occasion is the transfer of the throne at Hezekiah's death. The previous chapter ends with Hezekiah's water works recorded in the annals and then his death, with Manasseh succeeding him (2 Kings 20:20–21). The narrator sets the stage before he delivers the verdict.
The father matters to how this notice reads. Hezekiah was the king commended for trusting Yahweh, who removed the high places and destroyed the bronze serpent, whose reign was threatened by Assyria and extended by fifteen years. His son inherits a throne in Jerusalem and a covenant framework from Deuteronomy, where a king's faithfulness or apostasy shapes the nation's future. The long reign is stated without comment here; length alone is not praise. The narrator withholds evaluation until the next verses, and that delay is deliberate. A reader who knows the father arrives at 21:1 expecting good news.
Verses 2 and 3 supply the verdict immediately: Manasseh did evil in Yahweh's sight, followed the abominations of the nations, rebuilt the high places his father had destroyed, raised altars for Baal, made an Asherah as Ahab did, and worshiped the army of the sky. The contrast between father and son is the point the narrator is making. This passage describes a king's reign; it does not prescribe a parenting formula. Faithful parents are not promised faithful children, and an adult child's rebellion is not proof of a parent's failure. The text calls each generation to its own obedience before God.
The passage does not promise that godly parenting produces godly children, nor does it make parents responsible for an adult child's choices.
The Father named in the text
The opening of 2 Kings 21 reads like a ledger entry, and that is the point. The narrator records Manasseh's age, the length of his reign, the city where he ruled, and his mother's name, all in one breath. This is the fixed royal formula used throughout Kings, and it tells us the writer wants us to know exactly who this king was and where he came from. The father is not named in 21:1 itself. He is named one verse earlier, at the close of the previous chapter, where Hezekiah dies and his son takes the throne. Read the two together and the answer is plain: Manasseh's father was Hezekiah.
The phrase "slept with his fathers" at 2 Kings 20:21 is the standard idiom for a king's death and burial alongside his ancestors. It is not a doctrine about the afterlife dressed up in narrative clothing. In the same way, "reigned in his place" marks a lawful succession, a son formally taking up the seat his father vacated. Hephzibah's name belongs to that same administrative pattern, the queen mother recorded alongside the king's age and years. These are the ordinary bricks of royal record keeping, and they matter because they anchor the story in real time, real people and a real throne in Jerusalem.
The explicit link comes in 21:3, where the writer says Manasseh rebuilt what "Hezekiah his father" had destroyed. That single phrase settles the question and also sets up the tragedy of the chapter. A father who tore down high places is followed by a son who rebuilds them. Yet the text never tells us Hezekiah's faithfulness caused this, and it does not invite us to blame him for an adult son's choices. Scripture records the succession and the rebellion side by side without turning the record into a formula. Parents are called to faithfulness, not to control of outcomes that belong to God.
Hezekiah was manasseh's Father, and the text says so plainly
The question of who Manasseh's father was is answered by the text itself, not by inference. The closing notice of the previous reign reads, "Hezekiah slept with his fathers, and Manasseh his son reigned in his place" (2 Kings 20:21). Then the opening notice of the new reign gives the son's age, his mother's name, and the length of his rule in Jerusalem. Later in the same chapter the narrator refers back to Hezekiah as Manasseh's father by name, describing the high places the son rebuilt as those his father had destroyed. Two separate notices, one closing a reign and one opening it, join the two kings as father and son.
The surrounding material makes that line of descent the point, not a footnote. Hezekiah's reign is remembered for trust in Yahweh, for removing the high places and the bronze serpent, and for a deliverance from Assyria and fifteen added years. His story ends with the pool and the conduit that brought water into the city. Against that record the next verses turn immediately to evaluation: Manasseh was twelve when he began to reign, he reigned fifty-five years, the longest in the book, and he did evil in Yahweh's sight, following the abominations of the nations the Lord had driven out.
The narrator sets the reigns side by side because the covenant setting of Deuteronomy makes a king's faithfulness or apostasy shape a nation's future. The son rebuilt what the father had torn down, raised altars for Baal, and made an Asherah like Ahab. This is a historical and genealogical claim first: Manasseh was Hezekiah's son and successor, and his reign is judged evil. It is not a rule that faithful parenting guarantees faithful children, and it gives no ground for blaming parents for an adult child's rebellion. Grace runs the other way: God's mercy to Hezekiah did not pass automatically to his son.
Where readers disagree about manasseh's Father
Almost no careful reader disputes the basic answer. The same narrative names Hezekiah as Manasseh's father twice, once in the closing line of Hezekiah's reign and again in the opening verse of Manasseh's, where the son is twelve years old and his mother is Hephzibah. Kings does not leave the relationship to inference. The real disagreements sit around the numbers. Hezekiah was told he would receive fifteen added years, and Manasseh begins to reign at twelve. Readers who count the years forward and back arrive at different totals, and some propose a period of shared rule while others take the figures as the text gives them.
A second disagreement concerns Assyrian records and how they line up with the reigns in Kings. Some readers adjust the chronology to fit external evidence, positing overlapping reigns or a different way of reckoning the first year of a king. Others hold that the numbers should stand as written and that the difficulty lies in what we do not know rather than in the text. What stays central either way is that Kings presents Manasseh as Hezekiah's son, an apostate king whose reign provoked judgment. Reconstructed timelines are useful servants and poor masters; the church's authority is the text itself.
A third difference concerns 2 Chronicles, which reports a later repentance and restoration for Manasseh that Kings never mentions. Some readers let that account shape how they hear the earlier narrative; others insist Kings must be read on its own terms first. Both instincts have merit, and neither erases the other. What the passage will not support is a promise that faithful parenting guarantees faithful children. Hezekiah was a reforming king, and his son rebuilt what he tore down. Pastors should resist blaming parents for an adult child's rebellion. The text describes a real father and son; it does not turn that family into a formula.
A faithful Father, a wicked Son, and the king we still need
Hezekiah had just been told he would die, had prayed, and had been given fifteen more years. The narrator of 2 Kings 20:20–21 records his tunnel and pool, then closes his reign with the flat line that he slept with his fathers. The very next verse opens a new reign: "Manasseh was twelve years old when he began to reign, and he reigned fifty-five years in Jerusalem. His mother’s name was Hephzibah." 2 Kings 21:1. The son of the reformer inherits a throne, a city, and a covenant. Nothing in the text suggests Hezekiah's faithfulness purchased his son's. The account simply turns the page and shows what came next.
What came next is stated without softening. Manasseh rebuilt the high places his father had torn down, set up altars to Baal, made an Asherah, and worshiped the host of heaven (2 Kings 21:2–3). The narrator measures him against the nations God had driven out and against Ahab, the worst king Israel had produced. This is not a story about a father's failure to control a grown man. It is the story of a king who knew better and chose otherwise. Pastors should be careful here: this passage does not promise that faithful parenting guarantees faithful children, and it does not hand anyone grounds to blame a parent for an adult child's rebellion.
Still, the line of David does not end. It continues through a king who deserves none of it, and that is the mercy holding the whole book together. Later prophets name Manasseh's sins among the reasons Judah went into exile, which shows how seriously covenant unfaithfulness is weighed and why a righteous king was needed. Jesus is the true son of David who does right in Yahweh's sight and bears the judgment unfaithful kings and people deserved. The passage does not force that reading, but it makes a reader long for a son who does not repeat his father's failures or exceed them.
What faithful response looks like when the family line is mixed
Start with the plain fact the text gives: Hezekiah was Manasseh's father. The verse supplies the boy's age, the length of his reign, and his mother's name, then moves straight into the evil he did. Nothing here explains the gap between a father who tore down high places and a son who rebuilt them. That silence is worth sitting with. A godly parent does not guarantee a godly child, and this passage never asks us to trace Manasseh's rebellion back to Hezekiah's failures. Parents can teach, pray, and model repentance humbly, knowing outcomes rest with God and not with technique. Pastors should refuse to blame a mother or father for an adult child's choices, and refuse to promise that faithful parenting secures faithful children.
The text also invites honest self-examination. Manasseh rebuilt what his father had destroyed: the high places, the altars to Baal, the Asherah, the worship of the sky's army. He did not invent a new religion; he restored an old one. Ask what you are rebuilding that a previous generation pulled down, perhaps a habit, a grudge, or a compromise that seemed settled. Ask the harder question too: what are you tearing down that should stand, like a discipline, a friendship, or a plain obedience someone handed you? Grace does not make these questions optional. It makes them safe to ask, because we are not accepted by our family line or our record but by God's mercy in Christ.
Finally, notice the patience in the numbers. Manasseh began at twelve and reigned fifty-five years, and God kept working through that long stretch rather than ending the story at the first atrocity. That patience is real, but it is not a promise that every wayward season will be followed by a turnaround, and it is never a reason to treat sin lightly. Trust God's patience enough to keep praying for people who seem far off, and enough to keep obeying today. Let grace ground your obedience: not because your family name or your track record secures anything, but because the God who bore with Judah is the God who calls you to faithful, ordinary, hopeful living.
Biblical fidelity check
The question is settled inside the narrative itself. Second Kings 20:21 reports that Hezekiah died and that his son Manasseh succeeded him, and 21:3 calls Hezekiah Manasseh's father outright. The careful reading here is plain prose, not poetry or vision, so the risks are different: treating the death idiom as a statement about the afterlife, or importing a reconstructed timeline that overrules what the text says. The royal formula in 21:1, age, years, mother's name, is standard court record, not editorial decoration. Read in order, the passage names the father before it describes the son.
There is little real dispute that Hezekiah is the father, since two verses in one narrative say so. Where careful readers differ is chronology: how Manasseh's accession fits Hezekiah's added years and Assyrian records, with some proposing co-regencies and others taking the numbers as given. Readers also differ on how far Manasseh's later repentance in Chronicles should color Kings, which reports none of it. What stays central is that Kings presents Manasseh as Hezekiah's son and as an apostate king whose reign provoked judgment. The text, not reconstruction, is the church's authority.

Frequently asked questions
Who was Manasseh's father in the Bible?
Manasseh's father was Hezekiah, king of Judah. Second Kings 20:21 records that Hezekiah slept with his fathers and that Manasseh his son reigned in his place. Second Kings 21:3 then speaks of the high places which Hezekiah his father had destroyed, naming the relationship outright. The line is stated twice, once at the end of one reign and once inside the next, so the reader does not have to infer it.
How old was Manasseh when he became king, and how long did he reign?
Manasseh was twelve years old when he began to reign, and he reigned fifty-five years in Jerusalem. Second Kings 21:1 gives both figures in a single opening notice, along with his mother's name, Hephzibah. The length is striking next to his father's reign, and it means Manasseh's rule spanned more than half a century. The verse states the facts without commentary; the evaluation of his reign follows in the next verses.
Why does 2 Kings contrast Manasseh with his father Hezekiah?
The contrast shows how completely the reforms of one generation were undone in the next. Hezekiah had destroyed the high places, and 2 Kings 21:3 says Manasseh built them again, raised altars for Baal, made an Asherah, and worshiped the whole array of the sky. The parallel with Ahab, a northern king, signals how deep the departure went in Judah. The passage is describing the nation's spiritual condition, not delivering a rule about how children of godly parents will turn out.
