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

Behold, I will stand before thee there upon the rock in Horeb, and thou shall 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.

And the sons of Israel stripped themselves of their ornaments from mount Horeb onward.
