And Moses tended the flock of Jethro his father-in-law, the priest of Midian. And he led the flock behind the wilderness, and came to the mountain of God to Horeb.

Behold, I will stand before thee there upon the rock on Horeb; and thou shalt strike the rock, and there shall come water out of it, that the people may drink. And Moses did so before the eyes of the elders of Israel.

And the children of Israel stripped themselves of their ornaments at mount Horeb.
