Hebrews 7:4-6, 9-12

Now let me show you proof of how great this Melchizedek is: – Even though Abraham was the most honored and favored patriarch of all God’s chosen ones, he gave a tithe of the spoils of battle to Melchizedek. It would be understandable if Melchizedek had been a Jewish priest, for later on God’s people were required by law to support their priests financially, because the priests were their relatives and Abraham’s descendants. But Melchizedek was not Abraham’s Jewish relative, and yet Abraham still paid him a tithe. – Melchizedek imparted a blessing on mighty Abraham, who had received the promises of God.

It could even be said that Levi, the ancestor of every Jewish priest who received tithes, actually paid tithes to Melchizedek through Abraham. For although Levi was yet unborn, the seed from which Levi came was present in Abraham when he paid his tithe to Melchizedek. – If any of the Levitical priests who served under the law had the power to bring us into perfection, then why did God send Christ as Priest after the likeness of Melchizedek? He should have said, “After the likeness of Aaron.” – And furthermore, for God to send a new and different rank of priest, meant a new law would have had to be instituted even to allow it!
