Exodus 33:4-6

4 ¶ And when the people heard these evil tidings, they mourned: and no man did put on him his ornaments. 5 For the Lord had said unto Moses, Say unto the children of Israel, Ye are a stiffnecked people: I will come up into the midst of thee in a moment, and consume thee: therefore now put off thy ornaments from thee, that I may know what to do unto thee. 6 And the children of Israel stripped themselves of their ornaments by the mount Horeb.
