Exodus 17:6
Brenton's English Septuagint · Berean Standard Bible
Behold, I stand there before thou [come], on the rock in Choreb, and thou shalt smite the rock, and water shall come out from it, and the people shall drink. And Moses did so before the sons of Israel.
Behold, I will stand there before you by the rock at Horeb (note: Horeb is another name for Sinai.). And when you strike the rock, water will come out of it for the people to drink.” So Moses did this in the sight of the elders of Israel.
