Exodus 18:2-6

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

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:

4and the name of the other was Eliezer; forhe said, The God of my father was my help, and delivered me from the sword of Pharaoh.

5And Jethro, Moses’ father-in-law, came with his sons and his wife unto Moses into the wilderness where he was encamped, at the mount of God:

6and he said unto Moses, I, thy father-in-law Jethro, am come unto thee, and thy wife, and her two sons with her.
