Exodus 2:1

There went a man - Amram, son of Kohath, son of Levi, Exodus 6:16-20 . A daughter of Levi, Jochebed, sister to Kohath, and consequently both the wife and aunt of her husband Amram, Exodus 6:20 ; Numbers 26:59 . Such marriages were at this time lawful, though they were afterwards forbidden, Leviticus 18:12 . But it is possible that daughter of Levi means no more than a descendant of that family, and that probably Amram and Jochebed were only cousin germans . As a new law was to be given and a new priesthood formed, God chose a religious family out of which the lawgiver and the high priest were both to spring.
