Exodus 33:1-6 RSV

1 The LORD said to Moses, "Depart, go up hence, you and the people whom you have brought up out of the land of Egypt, to the land of which I swore to Abraham, Isaac, and Jacob, saying, 'To your descendants I will give it.'
2 And I will send an angel before you, and I will drive out the Canaanites, the Amorites, the Hittites, the Per'izzites, the Hivites, and the Jeb'usites.
3 Go up to a land flowing with milk and honey; but I will not go up among you, lest I consume you in the way, for you are a stiff-necked people."
4 When the people heard these evil tidings, they mourned; and no man put on his ornaments.
5 For the LORD had said to Moses, "Say to the people of Israel, 'You are a stiff-necked people; if for a single moment I should go up among you, I would consume you. So now put off your ornaments from you, that I may know what to do with you.'"
6 Therefore the people of Israel stripped themselves of their ornaments, from Mount Horeb onward.
