Exodus 17:1, 6
Then 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. / Behold, 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.
Numbers 20:11
Then Moses raised his hand and struck the rock twice with his staff, so that a great amount of water gushed out, and the congregation and their livestock were able to drink.
