Exodus 18 Intro: Jethro cometh to Moses -- His counsel is accepted.
1 When Jethro, the high 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.
