URI'JAH (flame of Jehovah). High priest in the reign of Ahaz, 2 Kgs 16:10-16; called Uriah in Isa 8:2; complied subserviently with the demand of the king to make an altar after the idolatrous pattern of that of Damascus, and to offer sacrifices on it. The son of Shemaiah of Kirjathjearim; prophesied in the days of Jehoiakim, and fled from the king's wrath to Egypt, but was seized there, brought back, and slain. Jer 26:20-23, U'RIM and THUM'MIM (light and perfection) denote some part of the high priest's apparel.
In Ex 28:15-30 it is prescribed that the Urim and Thummim shall be placed beneath the breastplate, in order to be on the high priest's heart when he goes in before the Lord; and when Aaron was arrayed, Moses himself put the Urim and Thummim into the breastplate. Lev 8:8. In the blessings of Moses he speaks of the Urim and Thummim as the crowning glory of the Levite tribe; and when Joshua is solemnly appointed to succeed him. Num 27:21, the high priest, Eleazar, is said to ask counsel for him after the judgment of Urim.
But nowhere in Scripture are the Urim and Thummim described, and, as Jewish tradition can give no information, we do not know what they really were.
