What were the Urim and the Thummim? Mentioned in 8:8 and in various other OT passages, the Urim and the Thummim remain a mystery to modern readers. All that is known is that they were worn on the garment of the high priest, and were used in seeking the Lord’s will on particular matters.
Sin offerings atoned for unintentional sins (4:1–35) and for sins of omission (5:1–13). The sacrificial animal was burned “outside of the camp” (4:12), rather than at the base of the altar. This foreshadowed the sacrificial death of Jesus Christ, who was crucified “outside the camp” (Heb. 13:13).
