And all the assembly of the children of Israel journeyed from the wilderness of Sin, according to their journeys, at the command of Jehovah; and they encamped in Rephidim; and there was no water for the people to drink.
And the people thirsted there for water; and the people murmured against Moses, and said, Why is it that thou hast brought us up out of Egypt, to kill us and our children and our cattle with thirst?
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.
And Moses' hands were heavy; then they took a stone, and put [it] under him, and he sat on it; and Aaron and Hur supported his hands, one on this side, and one on that side; and his hands were steady until the going down of the sun.
