The sons of Kohath: Amram, and Izhar, and Hebron, and Uzziel; and the years of the life of Kohath were one hundred thirty-three years.

Amram took Jochebed his father's sister to himself as wife; and she bore him Aaron and Moses: and the years of the life of Amram were a hundred and thirty-seven years.
