Exodus 18:2-4

2Now Jethro, Moses’s father-in-law, had taken in Zipporah, Moses’s wife, after he had sent her back,

3along with her two sons, one of whom was named Gershom (because Moses had said, “I have been a resident alien in a foreign land”)

4and the other Eliezer (because he had said, “The God of my father was my helper and rescued me from Pharaoh’s sword”).
