Exodus 17:6-8 Darby Translation (DARBY)
6 Behold, I will stand before thee there upon the rock on Horeb; and thou shalt strike the rock, and there shall come water out of it, that the people may drink. And Moses did so before the eyes of the elders of Israel.
7 And he called the name of the place Massah, and Meribah, because of the contention of the children of Israel, and because they had tempted Jehovah, saying, Is Jehovah among us, or not?
8 And Amalek came and fought with Israel in Rephidim.
