Now Moses kept the flock of Jethro his father-in-law, the priest of Midian: and he led the flock to the west side of the desert, and came to the mountain of God, even to Horeb.

Behold, I will stand before you there upon the rock in Horeb; and you shall strike 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 children of Israel stripped themselves of their ornaments by the mount Horeb.
