Exodus 18:1-5

Jethro, the priest of Midian, Moses’ father-in-law, heard of all that God had done for Moses and for Israel his people, how the LORD had brought Israel out of Egypt. Now Jethro, Moses’ father-in-law, had taken Zipporah, Moses’ wife, after he had sent her home, along with her two sons. The name of the one was Gershom (for he said, “I have been a sojourner in a foreign land”), and the name of the other, Eliezer (for he said, “The God of my father was my help, and delivered me from the sword of Pharaoh”). Jethro, Moses’ father-in-law, came with his sons and his wife to Moses in the wilderness where he was encamped at the mountain of God.
