1And all the congregation of the sons of Israel journey from the wilderness of Sin, on their journeys, by the command of YHWH, and encamp in Rephidim, and there is no water for the people to drink; 2and the people strive with Moses, and say, “Give us water, and we drink.” And Moses says to them, “Why do you strive with me? Why do you try YHWH?” 3And the people thirst for water there, and the people murmur against Moses, and say, “Why [is] this [that] you have brought us up out of Egypt to put us to death, also our sons and our livestock, with thirst?” 4And Moses cries to YHWH, saying, “What do I do to this people? Yet a little, and they have stoned me.” 5And YHWH says to Moses, “Pass over before the people, and take with you from [the] elderly of Israel, and take your rod in your hand, with which you have struck the River, and you have gone. 6Behold, I am standing before you there on the rock in Horeb, and you have struck on the rock, and waters have come out from it, and the people have drunk.” And Moses does so before the eyes of [the] elderly of Israel, 7and he calls the name of the place Massah, and Meribah, because of the strife of the sons of Israel, and because of their trying YHWH, saying, “Is YHWH in our midst or not?”

8And Amalek comes, and fights with Israel in Rephidim, 9and Moses says to Joshua, “Choose men for us, and go out, fight with Amalek: tomorrow I am standing on the top of the hill, and the rod of God in my hand.” 10And Joshua does as Moses has said to him, to fight with Amalek, and Moses, Aaron, and Hur have gone up [to] the top of the height; 11and it has come to pass, when Moses lifts up his hand, that Israel has been mighty, and when he lets his hands rest, that Amalek has been mighty. 12And the hands of Moses [are] heavy, and they take a stone and set [it] under him, and he sits on it, and Aaron and Hur have taken hold on his hands, one on this [side] and one on that [side]; and his hands are steadfast until the going in of the sun; 13and Joshua weakens Amalek and his people by the mouth of the sword.

14And YHWH says to Moses, “Write this, a memorial in a Scroll, and set [it] in the ears of Joshua, that I utterly wipe away the remembrance of Amalek from under the heavens”; 15and Moses builds an altar, and calls its name YHWH-Nissi, 16and says, “Because a hand [is] on the throne of YAH, war [is] to YHWH with Amalek from generation [to] generation.”
