Exodus 17:6-8 New Life Version (NLV)
6 See, I will stand before you there on the rock at Horeb. When you hit the rock, water will come out of it and the people will drink.” And Moses did so, with the leaders of Israel watching. 7 He called the name of the place Massah and Meribah because of the arguing of the people of Israel, and because they tested the Lord, saying, “Is the Lord among us or not?”
War with Amalek
8 Then Amalek came and fought against Israel at Rephidim.
