Exodus 33:4-6

33:4 When the people heard this troubling word they mourned; no one put on his ornaments. 33:5 For the Lord had said to Moses, “Tell the Israelites, ‘You are a stiff-necked people. If I went up among you for a moment, I might destroy you. Now take off your ornaments, that I may know what I should do to you.’” 33:6 So the Israelites stripped off their ornaments by Mount Horeb.
