1The entire Israelite community left the Wilderness of Sin, moving from one place to the next according to the LORD's command. They camped at Rephidim, but there was no water for the people to drink.
3But the people thirsted there for water, and grumbled against Moses. They said, "Why did you ever bring us out of Egypt to kill us and our children and our livestock with thirst?"
5The LORD answered Moses, "Go on ahead of the people and take some of the elders of Israel with you. Take the staff you struck the Nile with in your hand and go.
6I am going to stand there in front of you on the rock at Horeb; when you hit the rock, water will come out of it and the people will drink." Moses did this in the sight of the elders of Israel.
12When Moses' hands grew heavy, they took a stone and put it under him, and he sat down on it. Then Aaron and Hur supported his hands, one on one side and one on the other so that his hands remained steady until the sun went down.
14The LORD then said to Moses, "Write this down on a scroll as a reminder and recite it to Joshua: I will completely blot out the memory of Amalek under heaven."
