Ether 3:24 states that the stones (or Urim and Thummim) given by the Lord to the brother of Jared would "magnify to the eyes of men these things which ye shall write."
According to Randall Spackman, one of the most attractive, recent suggestions is that Urim is derived form the Assyrian u'uru, meaning "to send forth" and related to the noun urtu, meaning "a divine decision." Thummim may be related to the Assyrian noun tamatu, meaning "an oracle." Therefore the two terms might constitute a Hebrew hendiadys, a combination of "two formally co-ordinate terms--verbs, nouns, or adjectives--by 'and,'" which terms "express a single concept in which one of the components defines the other." The order of the terms is immaterial. Given the foregoing approach, the phrase "Urim and Thummim" could read as meaning "a divine decision in answer to a question" or "sacred answer," denoting the use to which the object was put. [Randall P. Spackman, The Jaredite Journey to America, p. 127]
According to Tom Cryer, the joining of heaven (the spiritual) and earth (the material) is shown by a heaven based triangle pointing downwards, manifesting God's focus upon man, and merging with an earth based triangle pointing upwards manifesting man's focus upon God. This merge forms a hexagram or a six-pointed star. This shape is known as the Magen David "Shield of David" or Seal of Solomon. The uniting of the two directions symbolize the blending of the physical with the spiritual. The interlaced triangles as seen on the flag of Israel is a sign of the Messiah, or Son of God.
Some Jewish historians have suggested that the ancient sign of Judaism originated by interlocking two crystals each in the form of an equilateral triangle. These crystals were two special stones called seerstones or interpreters or the Urim and Thummim, which is Hebrew for "lights and perfections" (see illustration). The sixteenth century Chilam Balam book from Yucatan refers to "the three cornered precious stone of grace" as being born "when the earth was submerged, when there was neither heaven nor earth." (Makenson) A pair of overlapping triangles crown the central circle of the Aztec calendar. A scepter used by Xipe Totec, an Ancient Mexican Deity, was "a staff with two triangles and a circular section through which he looks to see the futures." (Burdland:102) [Tom Cryer, Visual Sermons, pp. 68-69]
