The Mystery, Historical Context, and Significance of the Urim and Thummim
"God Speaks Through the Urim and Thummim," engraving by Jan Luyken, 1705 AD --- The projected Hebrew word means "emerald," one of the precious stones within the high priest's vestments (Exodus 28:18).
The Urim and Thummim are mentioned in Exodus 28 as part of the high priest's vestments. These are some of the most obscure things in the entire Bible, simply because, unlike many of the other religious components in the Old Testament, they’re not described in extensive detail.
Although we know what the Hebrew words “Urim” and “Thummim” mean, we lack a concrete understanding of what these two things actually are. The most traditional and literal translation is “Lights” and “Perfections,” but they’ve also been called “Revelations” and “Truths.” These translations have led some to believe that the Urim and Thummim aren’t necessarily physical objects, but abstract concepts. At the same time, God commanded Moses to put them “in” the breastplate of judgment, which could suggest that they are indeed physical objects, perhaps like the gemstones used in the high priest’s breastplate. Perhaps they are also gemstones, or simply ordinary stones; some scholars suggest that they were some type of special dice used for casting lots in a ritual to determine God’s will.
“And in the breastpiece of judgment you shall put the Urim and the Thummim, and they shall be on Aaron’s heart, when he goes in before the Lord. Thus Aaron shall bear the judgment of the people of Israel on his heart before the Lord regularly." (Exodus 28:30 ESV)
“And he shall stand before Eleazar the priest, who shall inquire for him by the judgment of the Urim before the Lord. At his word they shall go out, and at his word they shall come in, both he and all the people of Israel with him, the whole congregation." (Numbers 27:21 ESV)
“And when Saul inquired of the Lord, the Lord did not answer him, either by dreams, or by Urim, or by prophets." (1 Samuel 28:6 ESV)
In any case, the Urim and Thummim are theologically significant and applicable to us for several key reasons:
Foreshadowing Christ: The Hebrew words “Urim” and “Thummim” can be translated as “Lights” and “Perfections,” or as “Revelations” and “Truths.” In any case, all of these words describe Christ. He is the Light of the world (John 8:12), the Author and Perfecter of our faith (Hebrews 12:1-2), the Revelation of God's glory and nature (Hebrew 1:1-3), and the Way, the Truth, and the Life (John 14:6). The Urim and Thummim were used to make judgments, and Jesus will one day judge the living and the dead (2 Timothy 4:1).
Neglecting God: Similar to the infamous disappearance of the Ark of the Covenant, the Urim and Thummim have been lost to time, most likely around the time of the destruction of the First Temple and the Babylonian Exile. All of these holy relics in the Old Testament were provided by God for Israel’s benefit, but they essentially lost their privileges to use these sacred objects due to their disobedience, a solemn lesson on the consequences of sin. However, this goes even deeper…the cause of Israel’s disobedience was forgetting God’s ways and compromising morally with paganism. We too must remember to keep God’s ways, to not neglect our daily rhythms with Him, and to never compromise with sin. We will never be perfect, but we must be extremely deliberate to not turn away from God like the Israelites did when they apostatized and even forgot the Law of Moses (2 Kings 22:8-13).
The ancient Mesopotamians also had rituals to ascertain divine guidance for difficult decisions through casting lots. These lots were usually small stones, sticks, or bones within symbols or inscriptions on them. Not only does this fit the theory that the Urim and Thummim are inscribed stones, but it may also explain why the Bible is so unclear in describing these two religious elements, since the ancient readers would’ve been familiar with them. These types of random-chance rituals were used all over the ancient world, even in the Roman Empire, but they radically declined upon the rise of Christianity, which truly changed the world and its sense of spirituality. It’s also important to note that the Israelites were not instructed to use the other Mesopotamian rituals for determining divine will, such as trials by ordeal, extispicy (attempting to interpret divine messages from animal entrails), or astrology, which is completely and explicitly banned by the Torah (Deuteronomy 4:19, Deuteronomy 18:9-12).
There’s something significant about the fact that the Urim and Thummim are in front of the high priest’s heart (Exodus 28:30). This may suggest that the high priest’s heart must be in the right place in order to properly judge Israel.
The specific wording used to describe the way that Aaron “bears” the judgments of the people (Exodus 28:30) may also relate to the way in which Christ, our new High Priest, bore the judgments of our sins on the cross.
There’s an interesting parallel between the usage of the Urim and Thummim and the way that the apostles cast lots to select Matthias as the replacement for Judas (Acts 1:23-26). Both involve a ritual of random selection attributed to divine guidance. However, the rest of the New Testament records how the Holy Spirit is the main source of divine guidance for Christians, no longer an ancient ritual.
