The Lord spoke to Moses, saying: Take the staff, and assemble the congregation, you and your brother Aaron, and command the rock before their eyes to yield its water. Thus you shall bring water out of the rock for them; thus you shall provide drink for the congregation and their livestock.
So Moses took the staff from before the Lord, as he had commanded him. Moses and Aaron gathered the assembly together before the rock, and he said to them, “Listen, you rebels, shall we bring water for you out of this rock?” Then Moses lifted up his hand and struck the rock twice with his staff; water came out abundantly, and the congregation and their livestock drank.
At Meribah also known as Kadesh-barnea, in the South-West of the Dead Sea at the top corner of the Sinai peninsula, is a geological oddity: an enormous five-story high rock, with a thin split down the middle, which some believe to be the rock referenced in the old testament.
Of course, no good deed goes unpunished, and God, apparently angry at Moses for hitting the rock twice (or for some other seemingly small slight which is actually a point of some contention among biblical scholars), denied Moses the right to “bring this assembly into the land that I have given them.”
The split rock is located on the west side of Jebel el Lawz, and the name Meribah means strife.
