Hebrews 7:6-8

Amplified Bible

⁶ But this person [Melchizedek] who is not from their Levitical ancestry received tithes from Abraham and blessed him who possessed the promises [of God]. ⁷ Yet it is beyond all dispute that the lesser person is always blessed by the greater one. ⁸ Furthermore, here [in the Levitical priesthood] tithes are received by men who are subject to death; but in that case [concerning Melchizedek], they are received by one of whom it is testified that he ^[a]lives on [perpetually].
