Exodus 28:30
Context28:30 “You are to put the Urim and the Thummim 1 into the breastpiece of decision; and they are to be over Aaron’s heart when he goes in before the Lord. Aaron is to bear the decisions 2 of the Israelites over his heart before the Lord continually.
Exodus 28:43
Context28:43 These must be on Aaron and his sons when they enter 3 to the tent of meeting, or when they approach 4 the altar to minister in the Holy Place, so that they bear no iniquity and die. 5 It is to be a perpetual ordinance for him and for his descendants 6 after him. 7


[28:30] 1 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.
[28:30] 2 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
[28:43] 3 tn The construction for this temporal clause is the infinitive construct with the temporal preposition bet (ב) and the suffixed subjective genitive.
[28:43] 4 tn This construction is also the temporal clause with the infinitive construct and the temporal preposition bet (ב) and the suffixed subjective genitive.
[28:43] 5 tn The text has וְלאֹ־יִשְׂאוּ עָוֹן וָמֵתוּ (vÿlo’-yis’u ’avon vametu). The imperfect tense here introduces a final clause, yielding a purpose or result translation (“in order that” or “so that”). The last verb is the perfect tense with the vav consecutive, and so it too is equal to a final imperfect – but it would show the result of bearing the iniquity. The idea is that if they approached the holy things with a lack of modesty, perhaps like the pagans who have nakedness and sexuality as part of the religious ritual, they would pollute the holy things, and it would be reckoned to them for iniquity and they would die.
[28:43] 7 sn So the priests were to make intercession for the people, give decisions from God’s revealed will, enter his presence in purity, and represent holiness to Yahweh. The clothing of the priests provided for these functions, but in a way that brought honor and dignity. A priest was, therefore, to serve in purity, holiness, and fear (Malachi). There is much that can be derived from this chapter to form principles of spiritual leadership, but the overall point can be worded this way: Those whom God selects to minister to the congregation through intercessory prayer, divine counsel, and sacrificial worship, must always represent the holiness of Yahweh in their activities and demeanor.
