Exodus 1:2; Exodus 2:1; Exodus 6:16; Exodus 32:26; Exodus 32:28

2 Reuben, Simeon, Levi and Judah;

1 Now a man from the house of Levi went and married a daughter of Levi.

16 These are the names of the sons of Levi according to their generations: Gershon and Kohath and Merari; and the length of Levi's life was one hundred and thirty-seven years.

26 then Moses stood in the gate of the camp, and said, "Whoever is for the LORD , come to me!" And all the sons of Levi gathered together to him.

28 So the sons of Levi did as Moses instructed, and about three thousand men of the people fell that day.
