Exodus 17:11-16

11 And so it was, when Moses held up his hand, that Israel prevailed; and when he let down his hand, Amalek prevailed.
12 But Moses' hands became heavy; so they took a stone and put it under him, and he sat on it. And Aaron and Hur supported his hands, one on one side, and the other on the other side; and his hands were steady until the going down of the sun.
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."

INTRODUCTION TO EXODUS 17

The children of Israel coming to Rephidim, want water, and chide with Moses about it, who, crying to the Lord, is bid to smite the rock, from whence came water for them, and he named the place from their contention with him, Ex 17:1-7 at this place Amalek came and fought with Israel, who, through the prayer of Moses, signified by the holding up of his hands, and by the sword of Joshua, was vanquished, Ex 17:8-13, for the remembrance of which it was ordered to be recorded in a book, and an altar was built with this inscription on it, "Jehovahnissi": it being the will of God that Amalek should be fought with in every generation until utterly destroyed, Ex 17:14-16.
