[4] Along these lines, the Urim and Thummim are hypothesized to derive from the Tablet of Destinies worn by Marduk on his breast according to Babylonian religion.According to classical rabbinical literature, in order for the Urim and Thummim to give an answer, it was first necessary for the individual to stand facing the fully dressed high priest, and vocalise the question briefly and in a simple way, though it was not necessary for it to be loud enough for anyone else to hear it.[14] The first reference to Urim and Thummim in the Bible is the description in the Book of Exodus concerning the high priest's vestments;[15] the chronologically earliest passage mentioning them, according to textual scholars, is in the Book of Hosea,[16] where it is implied, by reference to the Ephod, that the Urim and Thummim were fundamental elements in the popular form of the Israelite religion,[3] in the mid 8th century BC.[26][27][28] In a passage from the part of the Book of Ezra which overlaps with the Book of Nehemiah, it is mentioned that individuals who were unable to prove, after the Babylonian captivity had ended, that they were descended from the priesthood before the captivity began, were required to wait until priests in possession of Urim and Thummim were discovered;[29] this would appear to confirm the statements in the Talmud that the Urim and Thummim had by then been lost.[1][4][3] Indeed, since the priestly source, which textual scholars date to a couple of centuries prior to the captivity, does not appear to know what the Urim and Thummim looked like, and there is no mention of the Urim and Thummim in the deuteronomic history beyond the death of David, scholars suspect that use of them decayed some time before the Babylonian conquest,[3] probably as a result of the growing influence of prophets at that time.[9] Joseph Smith, founder of the Latter Day Saint movement, said that he used interpreters in order to translate the Book of Mormon from the golden plates.[36] Smith extended the use of the term "Urim and Thummim" to describe the dwelling place of God, the earth in a future state, and the white stone mentioned in the Book of Revelation.[37] In accordance with the belief that Urim and Thummim translates to "Light and Truth", the Latin equivalent Lux et Veritas has been used for several university mottoes.Urim and Thummim itself is emblazoned in Hebrew across the open book pictured on the Yale University coat of arms, and the translation Lux et Veritas appears below on a banner.
