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.

God had agreed to lead the Israelites to the Promised Land, and drive out their enemies, but said that He would do so through an angel now, instead of personally dwelling among them. His instruction for the Israelites to remove their ornaments while He considered “what to do unto thee,” further reinforced the limbo of their situation. Rather than rejoicing at the positive aspects of God’s message, the Israelites took the more somber parts very hard.

Perhaps the Israelites would still be under the guidance of the Lord, but they were acutely aware of what had been lost. They were going to be guided by a steward now, rather than the King Himself, and that caused them to mourn.

This depressed uncertainty is well represented in the people removing their ornaments, meaning all of their jewelry and precious adornments. They were returning to a state of plain, unvarnished humility. Only by returning to their most basic state, with nothing earthly to get in the way, would they have any chance of reconnecting with the Lord.
