1Then the whole congregation of Israel left the Desert of Sin, moving from place to place as the LORD commanded. They camped at Rephidim, but there was no water for the people to drink.
3But the people thirsted for water there, and they grumbled against Moses: “Why have you brought us out of Egypt—to make us and our children and livestock die of thirst?”
5And the LORD said to Moses, “Walk on ahead of the people and take some of the elders of Israel with you. Take along in your hand the staff with which you struck the Nile, and go.
6Behold, I will stand there before you by the rock at Horeb. And when you strike the rock, water will come out of it for the people to drink.” So Moses did this in the sight of the elders of Israel.
9So Moses said to Joshua, “Choose some of our men and go out to fight the Amalekites. Tomorrow I will stand on the hilltop with the staff of God in my hand.”
12When Moses’ hands grew heavy, they took a stone and put it under him, and he sat on it. Then Aaron and Hur held his hands up, one on each side, so that his hands remained steady until the sun went down.
14Then the LORD said to Moses, “Write this on a scroll as a reminder and recite it to Joshua, because I will utterly blot out the memory of Amalek from under heaven.”
