2 Bible Verses about Fractions, One Tenth

It was this Melchizedek, King of Salem and Priest of the Most High God, who met Abraham returning from the slaughter of the kings, and gave him his blessing; and it was to him that Abraham allotted a tithe of all the spoil. The meaning of his name is 'King of Righteousness, ' and besides that, he was also King of Salem, which means 'King of Peace.' There is no record of his father, or mother, or lineage, nor again of any beginning of his days, or end of his life. In this he resembles the Son of God, and stands before us as a priest whose priesthood is continuous.read more.
Consider, then the importance of this Melchizedek, to whom even the Patriarch Abraham himself gave a tithe of the choicest spoils. Those descendants of Levi, who are from time to time appointed to the priesthood, are directed to collect tithes from the people in accordance with the Law--that is from their own Brothers, although they also are descended from Abraham. But Melchizedek, although not of this lineage, received tithes from Abraham, and gave his blessing to the very man who had God's promises. Now no one can dispute that it is the superior who blesses the inferior. In the one case the tithes are received by mortal men; in the other case by one about whom there is the statement that his life still continues. Moreover, in a sense, even Levi, who is the receiver of the tithes, has, through Abraham, paid tithes; for Levi was still in the body of his ancestor when Melchizedek met Abraham.

Alas for you, Teachers of the Law and Pharisees, hypocrites that you are! You pay tithes on mint, fennel, and caraway seed, and have neglected the weightier matters of the Law--justice, mercy, and good faith. These last you ought to have put into practice, without neglecting the first.
