We do have such a high priest who serves in the sanctuary, the true tabernacle set by the Lord

We do have such a high priest who serves in the sanctuary, the true tabernacle set by the Lord  

Heb 8:2

Now the main point of what we are saying is this: We do have such a high priest, who sat down at the right hand of the throne of the Majesty in heaven, ² and who serves in the sanctuary, the true tabernacle set up by the Lord, not by a mere human being.

Heb 8:6, 10

⁶ But in fact the ministry Jesus has received is as superior to theirs as the covenant of which he is mediator is superior to the old one, since the new covenant is established on better promises.

¹⁰ This is the covenant I will establish with the people of Israel
    after that time, declares the Lord.
I will put my laws in their minds
    and write them on their hearts.
I will be their God,
    and they will be my people.

1 Cor 9:18

¹⁷ If I preach voluntarily, I have a reward; if not voluntarily, I am simply discharging the trust committed to me. ¹⁸ What then is my reward? Just this: that in preaching the gospel I may offer it free of charge, and so not make full use of my rights as a preacher of the gospel.
