Exodus 33:1-6 New Revised Standard Version (NRSV)
The Command to Leave Sinai
33 The Lord said to Moses, “Go, leave this place, you and the people whom you have brought up out of the land of Egypt, and go to the land of which I swore to Abraham, Isaac, and Jacob, saying, ‘To your descendants I will give it.’ 2 I will send an angel before you, and I will drive out the Canaanites, the Amorites, the Hittites, the Perizzites, the Hivites, and the Jebusites. 3 Go up to a land flowing with milk and honey; but I will not go up among you, or I would consume you on the way, for you are a stiff-necked people.”
4 When the people heard these harsh words, they mourned, and no one put on ornaments. 5 For the Lord had said to Moses, “Say to the Israelites, ‘You are a stiff-necked people; if for a single moment I should go up among you, I would consume you. So now take off your ornaments, and I will decide what to do to you.’” 6 Therefore the Israelites stripped themselves of their ornaments, from Mount Horeb onward.
