2 Bible Verses about Fractions, One Tenth

FOR this Melchisedec, king of Salem, a priest of God most high, who met Abraham returning from the slaughter of the kings, and blessed him; to whom also Abraham gave a tenth share of all the spoil: being, as the interpretation of his name imports, first, King of righteousness, and then also King of Salem, that is, King of peace: without father, without mother, without genealogy, having neither beginning of days nor end of life, but in exact resemblance with the Son of God, abideth a priest for ever.read more.
Now observe how great is this [Melchisedec], to whom even Abraham the patriarch gave the tenth of the spoils. For they indeed of the sons of Levi, who are admitted to priesthood, have an order to receive tithes from the people according to the law, that is, of their brethren, though also sprung from the loins of Abraham. But he who derived not his genealogy from them, received tithes from Abraham, and blessed him who had the promises; but without all dispute the inferior receives benediction from the superior. And here indeed dying men receive the tithes, but there he hath a testimony borne to him that he liveth. And, if I may so say, through Abraham even Levi, who receiveth tithes, paid tithes. For he was as yet in the loins of his father when Melchisedec met him.

Wo unto you, scribes and Pharisees, hypocrites! for ye pay tithes of mint, and anise, and cummin, and have neglected the weightier precepts of the law, judgment, and mercy, and fidelity: these thing ought ye to have done, and not to leave the others undone.
