Hebrews 7:4, 8, 13, 15, 18

You can see how great Melchizedek was. Abraham, the great father, gave him a tenth of everything that he won in battle.

Priests receive a tenth, even though they are only men who live and then die. But Melchizedek, who received a tenth from Abraham, continues living, as the Scripture says.

We are saying these things about Christ, who belonged to a different tribe. No one from that tribe ever served as a priest at the altar.

And this becomes even more clear when we see that another priest comes who is like Melchizedek.

The old rule is now set aside, because it was weak and useless.
