Hebrews 7:9

We can say that through Abraham even Levi, who receives tithes, has paid tithes,

and blessed be God Most High, who has delivered your enemies into your hand." Abram gave him a tenth of all.

Therefore, as sin entered into the world through one man, and death through sin; and so death passed to all men, because all sinned.

Now consider how great this man was, to whom even Abraham, the patriarch, gave a tenth out of the best spoils.

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

"'All the tithe of the land, whether of the seed of the land or of the fruit of the trees, is Yahweh's. It is holy to Yahweh.
