The whole system changed under the New Covenant. Notice what happened:
Jesus said the temple would be utterly destroyed
"And, coming out, Jesus sent from the sanctuary. And His disciples approached to exhibit to Him the buildings of the sanctuary. Yet He, answering, said to them, 'Are you not observing all these? Verily, I am saying to you, Under no circumstances may a stone here be left on a stone, which shall not be DEMOLISHED.’" (Matt. 24:1-2).
Under the New Covenant, God does not dwell in temples made with hands,
"The God Who makes the world and all that is in it, He, the Lord inherent of heaven and earth, is NOT dwelling in temples made by hands..." (Acts 17:24).
The true believers under the New Covenant are now God’s temple,
"For YOU ARE THE TEMPLE OF THE LIVING GOD, according as God said, that I will be making My home and will be walking in them, and I will be their God, and they shall be My people" (II Cor. 6:16).
See also, (I Cor. 3:15 and I Cor. 1:19).
All theologians know that when the temple ceased, the priesthood officiating at the temple CEASED!
Each individual believer under the New Covenant forms a NEW priesthood,
"Yet you are a chosen race, a ‘ROYAL PRIESTHOOD’..." (I Peter 2:9).
How then, under the New Covenant, does a believer give a tenth, when he is supposed to give his all (Rom. 12:1), to a priesthood that does not exist, but now he himself is part of a priesthood (I Peter 2:9), at a temple that does not exist (Mat. 24:1-2), but rather he himself is the temple wherein God dwells?
No longer do we have priests with spiritual infirmities interceding for us, but rather we have Christ Jesus as our perfect intercessor and High Priest seated at the right hand of the Majesty in the heavens (Heb. 7:28-8:1).
