Exodus 18:2-6

Then Jethro, Moses’ father in law, took Zipporah, Moses’ wife, after he had sent her back,

And her two sons; of which the name of the one was Gershom; for he said, I have been an alien in a strange land:

And the name of the other was Eliezer; for the God of my father, said he, was mine help, and delivered me from the sword of Pharaoh:

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

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