In support of his theory that the Urim and Thummim of the Hebrew high-priest signified the stones of the breastplate worn on the sacred ephod, and should be rendered “perfectly brilliant,” Bellermann cites the passage in Ezekiel (chap, xxviii, verse 14), where he writes of “fiery stones” in treating of the royal splendors of the ruler of the great commercial city of Tyre. As to the oracular utterances of the high-priest when, clad in the ephod and wearing the glittering breastplate, he sought for the counsel of the Almighty, this author rejects the idea that the divine will was revealed by changes in the brilliancy of the stones, by casting of lots, or by a mysterious use of the ineffable name, the Tetragrammaton, J h w h (Jahweh), but believes that the answer to the questions was communicated to the high-priest by an inner voice, an inspiration similar to that vouchsafed to the great prophets of Israel.[509] A curious analogy to the use by Christians of fragments supposed to have come from the True Cross as amulets, was the employment by the Talmudic Jews of chips from an idol or from something that had been offered to an idol, for the same purpose. It is needless to say that this was severely condemned by the Rabbis. It is interesting to note the statements of Arab historians that the mummy of Cheops, the Pharaoh of the Great Pyramid, was decorated with a pectoral of precious stones. As the regal and priestly functions were united in the monarch, we may have here the first form of the high-priest’s breastplate. The Arab historian Abd er-Rahmân, writing in 829 A.D., states that Al Mamoun(813–833), son of Haroun-al-Raschid, entered the great pyramid and found the body of Cheops: In a stone sarcophagus was a green stone statue of a man, like an emerald, containing a human body, covered with a sheet of fine gold ornamented with a great quantity of precious stones; on the breast was a priceless sword, on the head a ruby as large as a hen’s egg, brilliant as a flame. I have seen the statue which contained the body; it was near the palace of Fôstat. Essentially the same account is given by Ebub Abd el-Holem, another Arab, who says: One saw beneath the summit of the pyramid a chamber with a hollow prison, in which was a statue of stone enclosing the body of a man, who had on the breast a pectoral of gold enriched by fine stones, and a sword of inestimable price, on the head a carbuncle the size of an egg, brilliant as the sun, on which were characters no man could read.
