Hebrews 7:5-10

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. And no one could deny the fact that the one who has the power to impart a blessing is superior to the one who receives it. – Although the Jewish priests received tithes, they all died—they were mortal. But Melchizedek lives on! – 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.
