Exodus 33:5

For the Lord had said unto Moses, Say unto the children of Israel, Ye are a stiff-necked people: I will come up into the midst of thee in a moment and consume thee; that had been the Lord's intention when His anger first flared up, Exodus 32:10; therefore now put off thy ornaments from thee, that I may know what to do unto thee. The Lord demanded this evidence of sincere repentance; for if they had refused and He had appeared in their midst for as much as a moment, their total destruction would have resulted.
