Hebrews 7:5-12 Catholic Public Domain Version (CPDV)

5. And indeed, those who are from the sons of Levi, having received the priesthood, hold a commandment to take tithes from the people in accord with the law, that is, from their brothers, even though they also went forth from the loins of Abraham.

6. But this man, whose lineage is not enumerated with them, received tithes from Abraham, and he blessed even the one who held the promises.

7. Yet this is without any contradiction, for what is less should be blessed by what is better.

8. And certainly, here, men who receive tithes still die; but there, he bears witness that he lives.

9. And so it may be said that even Levi, who received tithes, was himself a tithe through Abraham.

10. For he was still in the loins of his father, when Melchizedek met him.

11. Therefore, if consummation had occurred through the Levitical priesthood (for under it the people received the law), then what further need would there be for another Priest to rise up according to the order of Melchizedek, one who was not called according to the order of Aaron?

12. For since the priesthood has been transferred, it is necessary that the law also be transferred.
