For thus says the LORD, You shall not see wind, neither shall you see rain; yet that valley shall be filled with water, and you shall drink, both you and your livestock and your animals.
Behold, I will stand before you there on the rock in Chorev. You shall strike the rock, and water will come out of it, that the people may drink.* Moshe did so in the sight of the elders of Yisra'el.
They didn't thirst when he led them through the deserts; he caused the waters to flow out of the rock for them; he split the rock also, and the waters gushed out.
