Exodus 33:4-6

4And when the people heard this evil word, they mourned; and no man put on his ornaments.

5Now Jehovah had said to Moses, Say unto the children of Israel, Ye are a stiff-necked people: in one moment I will come up into the midst of thee and will consume thee. And now put off thine ornaments from thee, and I will know what I will do unto thee.

6And the children of Israel stripped themselves of their ornaments at mount Horeb.
