Exodus 18:1-6 (MHCC)

Exodus 18:1-6 (KJV):

1 When Jethro, the priest of Midian, Moses' father in law, heard of all that God had done for Moses, and for Israel his people, and that the LORD had brought Israel out of Egypt;
2 Then Jethro, Moses' father in law, took Zipporah, Moses' wife, after he had sent her back,
3 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:
4 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:
5 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:
6 And he said unto Moses, I thy father in law Jethro am come unto thee, and thy wife, and her two sons with her.

Jethro came to rejoice with Moses in the happiness of Israel, and to bring his wife and children to him. Moses must have his family with him, that while he ruled the church of God, he might set a good example in family government, 1Ti 3:5.
