Exodus 2:1 - Clarke's commentary and critical notes on the Bible

And there went a man of the house of Levi, and took to wife a daughter of Levi. 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.
