Exodus 18:2-5
2 After Moses had sent away his wife Zipporah, his father-in-law Jethro received her
3 and her two sons. One son was named Gershom, for Moses said, “I have become an alien in a foreign land”;
4 and the other was named Eliezer, for he said, “My father’s God was my helper; he saved me from the sword of Pharaoh.”
5 Jethro, Moses’ father-in-law, together with Moses’ sons and wife, came to him in the desert, where he was camped near the mountain of God.
