Hebrews 9 opens with a description of the earthly sanctuary and its contents. Instructions from Leviticus 16 begin in verse 7: “But into the second part the high priest went alone once a year, not without blood, which he offered for himself and for the people's sins committed in ignorance.” Verses 11-15 show Christ's fulfillment of the cleansing ritual and how He entered the Most Holy Place in heaven with His own blood. Verse 15 points out that our promise of eternal inheritance is based on His mediation; neither He nor we are awaiting Satan to fulfill any part of the sin offering. Verses 22-25 also explain Christ's cleansing of the heavenly sanctuary with His own blood, once for all, in contrast to the yearly purification of the physical sanctuary.
Comparing these explanations with the instruction in Leviticus 16, we see that both passages follow the same general order. Leviticus 16 begins with the instructions for the high priest on Atonement, just as Hebrews 2-9 presents Christ's superior High Priesthood. Next, Leviticus 16 proceeds to the slaughter of the first goat and the use of its blood to cleanse the sanctuary and holy objects. The bulk of Hebrews 9 explains Christ's role in fulfilling that.

Who Fulfills the Azazel Goat— Satan or Christ? (Part Three)
Christ became the inheritor of the promises made to Abraham because He alone of all men met all the conditions contained within the promises and the covenants that were made. He was perfect, blameless. Being in that position, He did something from which we benefit, which is explained here.
