the Urim: a sacred object the high priest carried in the pouch on his chest, paired with the Thummim and used to get a decision from God.
Every English Bible leaves this word untranslated and simply spells it out as "Urim." It names one of a pair of sacred objects, the Urim and the Thummim (תֻּמִּים), that the high priest carried in a pouch fastened to the front of his priestly garment (אֵפוֹד). Their one job was to give Israel an answer from God when a leader faced a question nobody could settle.
The Bible never says what they looked like or how they worked. Across its eight appearances the word does three different jobs: it names the objects themselves, it stands for the whole practice of putting a question to God through the priest, and in one much argued verse it names one of the two answers that could come back.
Two details do come through clearly. The answers were simple ones, of the yes or no, this man or that man kind, which is why many scholars picture something closer to a marked pair of lots (גּוֹרָל) than a message in words. And the right to use them belonged to the priest, not to the king or the prophet, which is what makes the silence in 1 Samuel 28:6 so frightening: Saul finds that God has stopped answering through every channel Israel had.
By the time the exiles came home the practice had lapsed. Ezra and Nehemiah both record families whose priestly ancestry could not be proved being set aside until a priest should stand up with Urim and Thummim, a wait the Bible never reports ending.

What the Urim and Thummim actually were, and how they delivered an answer.
- majorityA pair of marked lots that the priest cast or drew, capable of giving only one of two answers. This reading rests largely on the longer text of 1 Samuel 14:41, where the two are named as the alternative outcomes.; Julius Wellhausen, Der Text der Bucher Samuelis (1871); Johannes Lindblom, "Lot-Casting in the Old Testament," Vetus Testamentum 12 (1962); P.

- minorityNot a lot at all, but a stone whose miraculous light confirmed a revelation the high priest spoke, so that the answer could be more than a choice between two options.; Cornelis Van Dam, The Urim and Thummim: A Means of Revelation in Ancient Israel (1997)
