Thematic Bible: Water brought from the rock

And the LORD said unto Moses, "Go before the people, and take with thee of the elders of Israel: and thy rod wherewith thou smotest the river, take in thine hand and go. Behold, I will stand there before thee upon a rock in Horeb: and thou shalt smite the rock, and there shall come water out thereof, that the people may drink." And Moses did even so before the elders of Israel.
