Hebrews 8 context
Hebrews chapter 8 builds on the points made in chapter 7. Jesus' service as High Priest is superior, since He is given a better position and serves in a better location than the priests of the Old Covenant. This chapter sets up the idea of earthly things being shadows of heavenly things, especially when it comes to the temple and sacrifices. This leads into the focus of chapter 9, which is the superiority of Christ's sacrifice compared to those of the Levitical system (BibleRef).
