'Tithes' in the Bible

I fast twice in the week, I give tithes of all that I possess.

And verily they that are of the sons of Levi, who receive the office of the priesthood, have a commandment to take tithes of the people according to the law, that is, of their brethren, though they come out of the loins of Abraham:

But he whose descent is not counted from them received tithes of Abraham, and blessed him that had the promises.

And here men that die receive tithes; but there he receiveth them, of whom it is witnessed that he liveth.

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