Exodus 18:2-6

2And Jethro, Moses' father-in-law, took Zipporah, Moses' wife, after he had sent her back,

3and her two sons, of whom the name of the one was Gershom — for he said, I have been a sojourner in a foreign land,

4— and the name of the other, Eliezer — For the 1God of my father has been my help, and has delivered me from the sword of Pharaoh.

5And Jethro, Moses' father-in-law, came to Moses with his sons and his wife into the wilderness, where he encamped at the mountain of 2God.

6And he sent word to Moses: I, thy father-in-law Jethro, am come to thee, and thy wife, and her two sons with her.
