¹ tn Heb “a breastpiece of decision” (חֹשֶׁן מִשְׁפָּט, khoshen mishpat; so NAB). The first word, rendered “breastpiece,” is of uncertain etymology. This item was made of material similar to the ephod. It had four rows of three gems on it, bearing the names of the tribes. In it were the urim and thummim. J. P. Hyatt refers to a similar object found in the Egyptian reliefs, including even the twisted gold chains used to hang it from the priest (Exodus [NCBC], 282).

² sn The Urim and the Thummim were two objects intended for determining the divine will. There is no clear evidence of their size or shape or the material of which they were made, but they seem to have been familiar items to Moses and the people. The best example of their use comes from 1 Sam 14:36-42. Some have suggested from the etymologies that they were light and dark objects respectively, perhaps stones or sticks or some other object. They seem to have fallen out of use after the Davidic period when the prophetic oracles became popular. It may be that the title “breastpiece of judgment” indicates that these objects were used for making “decisions” (J. P. Hyatt, Exodus [NCBC], 283-84). U. Cassuto has the most thorough treatment of the subject (Exodus, 378-82); he lists several very clear rules for their uses gathered from their instances in the Bible, including that they were a form of sacred lot, that priests or leaders of the people only could use them, and that they were used for discovering the divine will in areas that were beyond human knowledge.

³ tn Or “judgment” (KJV, ASV, NASB, NRSV). The term is מִשְׁפָּט (mishpat), the same word that describes the breastpiece that held the two objects. Here it is translated “decisions” since the Urim and Thummim contained in the breastpiece represented the means by which the Lord made decisions for the Israelites. The high priest bore the responsibility of discerning the divine will on matters of national importance.
