And gavest them bread from heaven for their hunger, and broughtest forth water for them out of the rock for their thirst, and promisedst them that they should go in to possess the land which thou hadst sworn to give them.
Nehemiah 9:15
Exodus 17:6
Behold, I will stand before thee there upon the rock in Horeb; and thou shalt smite the rock, and there shall come water out of it, that the people may drink. And Moses did so in the sight of the elders of Israel.
