Exodus 18:2-6

² And Jethro, Moses' father-in-law, took Zipporah, Moses' wife, after he had sent her away, ³ And her two sons, one of whom was named Gershom, for he said, I have been living in a strange land: ⁴ And the name of the other was Eliezer, for he said, The God of my father was my help, and kept me safe from the sword of Pharaoh: ⁵ And Jethro, Moses' father-in-law, came with his sons and his wife to where Moses had put up his tent in the waste land, by the mountain of God. ⁶ And he said to Moses, I, your father-in-law, have come to you, with your wife and your two sons.
