Hebrews 8:1-5 NKJV
Now this is the main point of the things we are saying: We have such a High Priest, who is seated at the right hand of the throne of the Majesty in the heavens, a Minister of the sanctuary and of the true tabernacle which the Lord erected, and not man.
For every high priest is appointed to offer both gifts and sacrifices. Therefore it is necessary that this One also have something to offer. For if He were on earth, He would not be a priest, since there are priests who offer the gifts according to the law; who serve the copy and shadow of the heavenly things, as Moses was divinely instructed when he was about to make the tabernacle. For He said, “See that you make all things according to the pattern shown you on the mountain.”
