Exodus 18:1-3

Now 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. Jethro, Moses’ father-in-law, took Moses’ wife Zipporah, after he had sent her away, and her two sons, of whom one was named Gershom, for Moses said, “I have been a sojourner in a foreign land.”
