Then Amalek came and made war on Israel in Rephidim.

And Moses said to Joshua, Get together a band of men for us and go out, make war on Amalek: tomorrow I will take my place on the top of the hill with the rod of God in my hand.

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

Now while Moses' hand was lifted up, Israel was the stronger: but when he let his hand go down, Amalek became the stronger.

And Joshua overcame Amalek and his people with the sword.

And the Lord said to Moses, Make a record of this in a book, so that it may be kept in memory, and say it again in the ears of Joshua: that all memory of Amalek is to be completely uprooted from the earth.

For he said, The Lord has taken his oath that there will be war with Amalek from generation to generation.
