URIM AND THUMMIM: (light and perfection). When the Jewish exiles were met on their return from Babylon by a question which they had no data for answering, they agreed to postpone the settlement of the difficulty till there should rise up "a priest with Urim and Thummim." (Ezra 2:63; Nehemiah 7:65) The inquiry what those Urim and Thummim themselves were seems likely to wait as long for a final and satisfying answer. On every side we meet with confessions of ignorance. Urim means "light," and Thummim "perfection." Scriptural statements. --The mysterious words meet us for the first time, as if they needed no explanation, in the description of the high Priest’s apparel. Over the ephod there is to be a "breastplate of judgment" of gold, scarlet, purple and fine linen, folded square and doubled, a "span" in length and width. In it are to be set four rows of precious stones, each stone with the name of a tribe of Israel engraved on it, that Aaron "may bear them on his heart." Then comes a further order. In side the breastplate, as the tables of the covenant were placed inside the ark, (Exodus 25:16; 28:30) are to be placed "the Urim and the Thummim," the light and the perfection; and they too are to be on Aaron’s heart when he goes in before the Lord. (Exodus 28:15-30) Not a word describes them. They are mentioned as things-already familiar both to Moses and the people, connected naturally with the functions of the high priest as mediating between Jehovah and his people. The command is fulfilled. (Leviticus 8:8) They pass from Aaron to Eleazar with the sacred ephod and other pontificalia . (Numbers 20:28) When Joshua is solemnly appointed to succeed the great hero-law-giver he is bidden to stand before Eleazar, the priest, "who shall ask counsel for him after the judgment of U
rim," and this counsel is to determine the movements of the host of Israel. (Numbers 27:21) In the blessings of Moses they appear as the crowning glory of the tribe of Levi: "thy Thummim and thy Urim are with thy Holy One." (33:8,9) In what way the Urim and Thummim were consulted is quite uncertain. Josephus and the rabbins supposed that the stones gave out the oracular answer by preternatural illumination; but it seems to be far simpler and more in agreement with the different accounts of inquiries made by Urim and Thummim, (1 Samuel 14:3,18,19; 23:2,4,9,11,12; 28:6; Judges 20:28; 2 Samuel 5:23) etc., to suppose that the answer was given simply by the word of the Lord to the high priest comp. (John 11:51) when, clothed with the ephod and the breastplate, he had inquired of the Lord. Such a view agrees with the true notion of the breastplate.
