Who Was Moses' Father? Amram in Exodus 6:20
Exodus 6:20 answers the question directly: Moses' father was Amram, a Levite descended from Kohath. The same verse names Jochebed as Moses' mother and notes that she was Amram's father's sister.
Numbers 26:59: Jochebed, Not Caleb's Mother
Numbers 26:59 answers a different question than the one many readers bring to it. The verse names Jochebed as the mother of Aaron, Moses, and Miriam, and it says nothing about Caleb's mother.
