Thematic Bible: Water brought from the rock

And the Lord said to Moses, Pass on before the people, and take with you some of the elders of Israel; and take in your hand the rod with which you smote the river [Nile], and go. Behold, I will stand before you there on the rock at [Mount] Horeb; and you shall strike the rock, and water shall come out of it, that the people may drink. And Moses did so in the sight of the elders of Israel.
