Thematic Bible: Water brought from the rock

Jehovah said to Moses: Go in front of the people. Take the elders of Israel with you. Take your rod with which you struck the river, in your hand, and go. Behold! I will stand before you there upon the rock in Horeb. Strike the rock and water will come out of it. Then the people may drink. Moses did this in the sight of the elders of Israel.
