Exodus Chapter 18 Verse 1When 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;

And he called the name of the place Massah, and Meribah, because of the chiding of the children of Israel, and because they tempted the LORD, saying, Is the LORD among us, or not?

Then came Amalek, and fought with Israel in Rephidim.

And Moses said unto Joshua, Choose us out men, and go out, fight with Amalek: to morrow I will stand on the top of the hill with the rod of God in mine hand.

So Joshua did as Moses had said to him, and fought with Amalek: and Moses, Aaron, and Hur went up to the top of the hill.

And it came to pass, when Moses held up his hand, that Israel prevailed: and when he let down his hand, Amalek prevailed.

But Moses' hands [were] heavy; and they took a stone, and put [it] under him, and he sat thereon; and Aaron and Hur stayed up his hands, the one on the one side, and the other on the other side; and his hands were steady until the going down of the sun.

And Joshua discomfited Amalek and his people with the edge of the sword.

And the LORD said unto Moses, Write this [for] a memorial in a book, and rehearse [it] in the ears of Joshua: for I will utterly put out the remembrance of Amalek from under heaven.

And Moses built an altar, and called the name of it Jehovahnissi:

For he said, Because the LORD hath sworn [that] the LORD [will have] war with Amalek from generation to generation.

Then Jethro, Moses' father in law, took Zipporah, Moses' wife, after he had sent her back,

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:

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:

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:

And he said unto Moses, I thy father in law Jethro am come unto thee, and thy wife, and her two sons with her.

And Moses went out to meet his father in law, and did obeisance, and kissed him; and they asked each other of [their] welfare; and they came into the tent.

And Moses told his father in law all that the LORD had done unto Pharaoh and to the Egyptians for Israel's sake, [and] all the travail that had come upon them by the way, and [how] the LORD delivered them.

And Jethro rejoiced for all the goodness which the LORD had done to Israel, whom he had delivered out of the hand of the Egyptians.

And Jethro said, Blessed [be] the LORD, who hath delivered you out of the hand of the Egyptians, and out of the hand of Pharaoh, who hath delivered the people from under the hand of the Egyptians.

Now I know that the LORD [is] greater than all gods: for in the thing wherein they dealt proudly [he was] above them.
