Exodus 6:18
And the sons of Kohath; Amram, and Izhar, and Hebron, and Uzziel: and the years of the life of Kohath were an hundred thirty and three years. And the sons of Kohath; Amram, and Izhar, and Hebron, and Uzziel: and the years of the life of Kohath were an hundred thirty and three years.
Kohath had four sons — Amram, Izhar, Hebron, and Uzziel — and lived one hundred thirty-three years. In the genealogy reaching from Jacob's family to Moses, Kohath's line continues through Amram, who with Jochebed became the parents of Moses, making Amram the father of Moses and Aaron. The long lives in Levi's family allowed successive generations to pass on their religious knowledge.
The verse stands in the opening of Israel's deliverance from oppression and bondage under the full power of Egypt set against them. That deliverance points toward triumph beyond the Red Sea with Egypt's host overthrown. This saving of Israel was God's mighty work as creative power manifested over again, such as was never done in the saving of any nation.
The verse belongs to the mainly historical first division of Exodus in chapters 1-18, specifically to the section in chapters 5-10 concerning the interviews with Pharaoh, the contest with his magicians, and the infliction of the plagues. It belongs to the portion in chapters 5-8 that tells of warnings and plagues. It belongs to the account in chapters 1-12 of God's call to Egypt three and one-half millennia ago when Egypt was the world's greatest ruling kingdom, and it lists among the few descendants of the nomadic patriarch Abraham who had sought supplies from Egypt's granaries.
