Exodus 17:9-16

9 and Moses saith unto Joshua, `Choose for us men, and go out, fight with Amalek: to-morrow I am standing on the top of the hill, and the rod of God in my hand.'
10 And Joshua doth as Moses hath said to him, to fight with Amalek, and Moses, Aaron, and Hur, have gone up [to] the top of the height;
11 and it hath come to pass, when Moses lifteth up his hand, that Israel hath been mighty, and when he letteth his hands rest, that Amalek hath been mighty.
12 And the hands of Moses [are] heavy, and they take a stone, and set [it] under him, and he sitteth on it: and Aaron and Hur have taken hold on his hands, on this side one, and on that one, and his hands are stedfast till the going in of the sun;
13 and Joshua weakeneth Amalek and his people by the mouth of the sword.
14 And Jehovah saith unto Moses, `Write this, a memorial in a Book, and set [it] in the ears of Joshua, that I do utterly wipe away the remembrance of Amalek from under the heavens;'
15 and Moses buildeth an altar, and calleth its name Jehovah-Nissi,
16 and saith, `Because a hand [is] on the throne of Jah, war [is] to Jehovah with Amalek from generation -- generation.'

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.
