These verses contain two references to the second function prefigured in the azazel and performed by the Messiah, that of bearing sin. As it says in Leviticus 16:22, the azazel was to bear on itself all the iniquities of the people. Its primary role was bearing sins as a substitute. Verse 11 teaches that justification results from the Messiah bearing iniquities. Verse 12 uses the prophetic past-tense, saying that the Messiah bore the sins of many. When this prophecy was given, His work was as good as done. Here are two more clear scriptures about Christ that directly link to the role of the azazel. We are already on our third witness of a Messianic fulfillment of the azazel.
We went through the scriptural fulfillment of the azazel last time, so I will just mention the verses. These all correspond with what happens with the live goat:
This is how sins are removed - through Jesus Christ becoming sin and being separated from the Father for what must have seemed like eternity. Like the first goat, His sacrifice opened the way into the Holy of Holies. His sinless blood has given us access to and satisfied the Most High God. Like the second goat, Jesus also bore our sins. Through piercing, bruising, and wounding while hanging on a tree for hours outside the gate, our transgressions are removed as far as east is from the west (Psalm 103:12).
