New King James Version (NKJV)
Exodus 17
13 So Joshua defeated Amalek and his people with the edge of the sword.
14 Then the Lord said to Moses, "Write this for a memorial in the book and recount it in the hearing of Joshua, that I will utterly blot out the remembrance of Amalek from under heaven."
15 And Moses built an altar and called its name, The-Lord-Is-My-Banner;
16 for he said, "Because the Lord has sworn: the Lord will have war with Amalek from generation to generation."
Exodus 18
1 And Jethro, the priest of Midian, Moses’ father-in-law, heard of all that God had done for Moses and for Israel His people--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 with her two sons, of whom the name of one was Gershom (for he said, "I have been a stranger in a foreign land")
4 and the name of the other was Eliezer (for he said, "The God of my father was my help, and delivered me from the sword of Pharaoh");
5 and 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.
6 Now he had said to Moses, "I, your father-in-law Jethro, am coming to you with your wife and her two sons with her."
7 So Moses went out to meet his father-in-law, bowed down, and kissed him. And they asked each other about their well-being, and they went into the tent.
