Now Moses was keeping the flock of Jethro (Reuel) his father-in-law, the priest of Midian; and he led his flock to the west side of the wilderness and came to Horeb (Sinai), the mountain of God.

And God said, “Certainly I will be with you, and this shall be the sign to you that it is I who have sent you: when you have brought the people out of Egypt, you shall serve and worship God at this mountain.”

The Lord said to Aaron, “Go into the wilderness to meet Moses.” So he went and met him at the mountain of God (Sinai) and kissed him.

Behold, I will stand before you there on the rock at Horeb; there you shall strike the rock, and water will come out of it, so that the people may [have something to] drink.” And Moses did so in the sight of the elders of Israel.

Then Jethro, his father-in-law, came with Moses’ sons and his wife to [join] Moses in the wilderness where he was camped, at the mountain of God [that is, Mt. Sinai in Horeb].

So the Israelites left off all their ornaments [in repentance], from Mount Horeb (Sinai) onward.
