Exodus 6:23
And Aaron took him Elisheba, daughter of Amminadab, sister of Naashon, to wife; and she bare him Nadab, and Abihu, Eleazar, and Ithamar. And Aaron took him Elisheba, daughter of Amminadab, sister of Naashon, to wife; and she bare him Nadab, and Abihu, Eleazar, and Ithamar.
Exodus means the going out, referring to the departure of Israel from Egypt, and this verse stands in its history part. That history part is the mainly historical division forming the first division of the book in chapters 1 to 18. Within that division, chapters 5 to 10 record the interviews with Pharaoh, the contest with his magicians, and the infliction of the plagues.
The verse belongs to the detailed story of the great deliverance from bitter bondage and oppression after Israel grew more and mightier than the Egyptians. It is part of showing how the family comfortably settled in Egypt became a nation with thorough organization, efficient leadership, a complete code of laws, and an established form of worship. It stands where the life of Moses from his rescue in infancy as chosen leader is of absorbing interest.
