Exodus 33:4-6

Amplified Bible

⁴ When the people heard this sad word, they mourned, and none of them put on his ornaments. ⁵ For the Lord had said to Moses, “Say to the sons of Israel, ‘You are a stiff-necked (stubborn, rebellious) people! If I should come among you for one moment, I would destroy you. Now therefore, [penitently] take off your ornaments, so that I may know what to do with you.’” ⁶ So the Israelites left off all their ornaments [in repentance], from Mount Horeb (Sinai) onward.
