Exodus 33:1-6

1And Jehovah spake unto Moses, Depart, go up hence, thou and the people that thou hast brought up out of the land of Egypt, unto the land of which I sware unto Abraham, to Isaac, and to Jacob, saying, Unto thy seed will I give it: 2and I will send an angel before thee; and I will drive out the Canaanite, the Amorite, and the Hittite, and the Perizzite, the Hivite, and the Jebusite: 3unto a 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. 4And when the people heard these evil tidings, they mourned: and no man did put on him his ornaments. 5And Jehovah 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. 6And the children of Israel stripped themselves of their ornaments from mount Horeb onward.
