28:30 “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.
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.

But there will inevitably be iniquity involved. U. Cassuto explains that Aaron “will atone for all the transgressions committed in connection with the order of the service, the purity of the consecrated things, or the use of the holy gifts, for the declaration engraved on the plate will prove that everything was intended to be holy to the Lord, and if aught was done irregularly, the intention at least was good” (Exodus, 385).
4 tn The clause reads: “according to/by all the gifts of their holiness.” The genitive is an attributive genitive, the suffix on it referring to the whole bound construction – “their holy gifts.” The idea of the line is that the people will consecrate as holy things gifts they bring to the sanctuary.
5 tn This clause is the infinitive construct with the lamed preposition, followed by the prepositional phrase: “for acceptance for them.” This infinitive provides the purpose or result of the act of wearing the dedicatory frontlet – that they will be acceptable.
