For the LORD had said to Moses, “Tell the Israelites, ‘You are a stiff-necked people. If I should go with you for a single moment, I would destroy you. Now take off your jewelry, and I will decide what to do with you.’”
Jewish Publication Society of America Version (JPS1917) - Exodus 33:5 >And the LORD said unto Moses: 'Say unto the children of Israel: Ye are a stiffnecked people; if I go up into the midst of thee for one moment, I shall consume thee; therefore now put off thy ornaments from thee, that I may know what to do unto thee.'
