Hebrews 7:5-9

5Moses’ Teachings say that members of the tribe of Levi who become priests must receive a tenth of everything from the people. The priests collect it from their own people, Abraham’s descendants.

6Although Melchizedek was not from the tribe of Levi, he received a tenth of everything from Abraham. Then Melchizedek blessed Abraham, who had God’s promises.

7No one can deny that the more important person blesses the less important person.

8Priests receive a tenth of everything, but they die. Melchizedek received a tenth of everything, but we are told that he lives.

9We could even say that when Abraham gave Melchizedek a tenth of everything, Levi was giving a tenth of everything. Levi gave, although later his descendants would receive a tenth of everything.
