Hebrews 7:9

And, so to speak, Levi also, the man who receives tithes, has paid tithes through Abraham,

And blessed be God Most High, who has delivered thine enemies into thy hand. And [Abram] gave him a tenth of all.

Because of this, just as through one man sin entered into the world, and death through sin, so also death passed to all men, in that all sinned.

And notice how great this man was, to whom also the patriarch Abraham gave a tenth out of the best spoils.

Treasury of Scripture Knowledge

And as I may so say, Levi also, who receiveth tithes, payed tithes in Abraham.

And all the tithe of the land, whether of the seed of the land, or of the fruit of the tree, is LORD's; it is holy to LORD.
