2 Bible Verses about Fractions, One Tenth

For this Melchisedec, king of Salem, priest of the most high God, who met Abraham returning from the slaughter of the kings, and blessed him, to whom also Abraham divided the tenth of all his spoils; being in the first place, by interpretation of his name, king of righteousness, and moreover king of Salem, which is king of peace; without father, without mother, without genealogy, having neither beginning of days recorded, nor end of life, but resembling the Son of God, remaineth a priest continually.read more.
Now consider how great a man this was, to whom even the patriarch Abraham gave the tenth of the spoils. And those indeed of the sons of Levi, who receive the priesthood, have a commandment according to the law to take tithes of the people, that is, of their brethren, though they came out of the loins of Abraham: but he, whose pedigree is not reckoned among them, took tithes of Abraham, and blessed him that had the promises. Now without all contradiction the inferior is blessed by the superior: besides, here men that die receive tithes; but there he of whom it is testified that he liveth. And (as one may say) even Levi, who receiveth tithes, paid tithes in Abraham: for he was yet in the loins of his father, when Melchisedec met him.

Wo unto you scribes and pharisees, hypocrites, who tithe even your mint, and anise, and cummin, but neglect the weightier matters of the law, judgement, mercy, and fidelity: these ye ought undoubtedly to practise, and not to omit the others.
