'Percentage' in the Bible

Return their fields, vineyards, olive groves, and houses to them immediately, along with the percentage of the money, grain, new wine, and olive oil that you have been assessing them.”

if he does not charge interest or take a percentage of increase [on what he lends in compassion], if he keeps his hand from sin and executes true justice between man and man,

and charges interest and takes [a percentage of] increase on what he has loaned; will he then live? He will not live! He has done all these disgusting things, he shall surely be put to death; his blood will be on his own head.

In you they have accepted bribes to shed blood; you have taken [forbidden] interest and [a percentage of] profits, and you have injured your neighbors for gain by oppression and extortion, and you have forgotten Me,” says the Lord God.
