Kutoka 17:6

Huko nitasimama mbele yako karibu na mwamba wa Horebu. Uupige mwamba na maji yatatoka ndani yake kwa ajili ya watu kunywa.” Kwa hiyo Mose akafanya haya mbele ya wazee wa Israeli.

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.
