Discovery BoxExodus 16:8 
Context16:8 Moses said, “You will know this 1 when the Lord gives you 2 meat to eat in the evening and bread in the morning to satisfy you, because the Lord has heard your murmurings that you are murmuring against him. As for us, what are we? 3 Your murmurings are not against us, 4 but against the Lord.”
Exodus 28:30
Context28:30 “You are to put the Urim and the Thummim 5 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 6 of the Israelites over his heart before the Lord continually.
Exodus 34:10
Context34:10 He said, “See, I am going to make 7 a covenant before all your people. I will do wonders such as have not been done 8 in all the earth, nor in any nation. All the people among whom you live will see the work of the Lord, for it is a fearful thing that I am doing with you. 9
1 tn “You will know this” has been added to make the line smooth. Because of the abruptness of the lines in the verse, and the repetition with v. 7, B. S. Childs (Exodus [OTL], 273) thinks that v. 8 is merely a repetition by scribal error – even though the versions render it as the MT has it. But B. Jacob (Exodus, 447) suggests that the contrast with vv. 6 and 7 is important for another reason – there Moses and Aaron speak, and it is smooth and effective, but here only Moses speaks, and it is labored and clumsy. “We should realize that Moses had properly claimed to be no public speaker.”
2 tn Here again is an infinitive construct with the preposition forming a temporal clause.
3 tn The words “as for us” attempt to convey the force of the Hebrew word order, which puts emphasis on the pronoun: “and we – what?” The implied answer to the question is that Moses and Aaron are nothing, merely the messengers.
4 tn The word order is “not against us [are] your murmurings.”
5 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.
6 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
7 tn Here again is a use of the futur instans participle; the deictic particle plus the pronoun precedes the participle, showing what is about to happen.
8 tn The verb here is בָּרָא (bara’, “to create”). The choice of this verb is to stress that these wonders would be supernaturally performed, for the verb is used only with God as the subject.
9 sn The idea is that God will be doing awesome things in dealing with them, i.e., to fulfill his program.
