Urim and Thummim

Urim and Thummim are named as objects placed inside Aaron’s Breastplate of Judgment, where they are associated with his priestly duty to bear the judgment of the children of Israel before the LORD. The text specifies their placement and ritual setting but does not explain their appearance or method of use.

Placement in the Breastplate

The Breastplate of Judgment was a square, doubled piece of skilled work made from gold, blue, purple, scarlet, and fine linen. It held twelve precious stones, each engraved with the name of one of the tribes of Israel. Gold chains and rings attached it securely to the ephod, so that it would not come loose.

Urim and Thummim were to be put inside this breastplate. They were therefore set within the garment that bore the names of the tribes, rather than described as independent furnishings of the sanctuary.

Priestly Function and Limits of the Description

Aaron was to wear the breastplate over his heart when he entered the holy place. The passage connects this placement with his responsibility to bear Israel’s judgment before the LORD continually, making the objects part of the priestly arrangement through which the people were represented in the sanctuary.

The instructions give no account of the objects’ form, material, or specific operation. Their significance in this passage rests on their position within the Breastplate of Judgment and their association with Aaron’s representative office, not on an explicitly narrated act of consultation.
