Now the main point in what we are saying is this: we have such a high priest, one who is seated at the right hand of the throne of the Majesty in the heavens,
a minister in the sanctuary and the true tent that the Lord, and not any mortal, has set up.
References for Hebrews 8:2

They offer worship in a sanctuary that is a sketch and shadow of the heavenly one; for Moses, when he was about to erect the tent, was warned, "See that you make everything according to the pattern that was shown you on the mountain."
References for Hebrews 8:5
But Jesus has now obtained a more excellent ministry, and to that degree he is the mediator of a better covenant, which has been enacted through better promises.
