Exodus 33:1-6

1 And the LORD said unto Moses, Depart and go up from here, thou and the people which thou hast brought up out of the land of Egypt unto the land which I swore unto Abraham, Isaac, and Jacob, saying, Unto thy seed will I give it.
2 (And I will send an angel before thee; and I will drive out the Canaanite, the Amorite, the Hittite, the Perizzite, the Hivite, and the Jebusite.)
3 Unto the land flowing with milk and honey; for I will not go up in the midst of thee; for thou art a stiffnecked people lest I consume thee in the way.
4 And when the people heard these evil tidings, they mourned, and no one put on their ornaments.
5 For the LORD had said unto Moses, Say unto the sons 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 Then the sons of Israel stripped themselves of their ornaments from Mount Horeb on.
