Exodus 33:4

2I will send an angel before you; and I will drive out the Canaanite, the Amorite, and the Hittite, and the Perizzite, the Hivite, and the Jebusite.

3Go to a land flowing with milk and honey; but I will not go up among you, for you are a stiff-necked people, lest I consume you on the way.”

4When the people heard this evil news, they mourned; and no one put on his jewelry.

5The LORD had said to Moses, “Tell the children of Israel, ‘You are a stiff-necked people. If I were to go up among you for one moment, I would consume you. Therefore now take off your jewelry from you, that I may know what to do to you.’”

6The children of Israel stripped themselves of their jewelry from Mount Horeb onward.
