'Interest' in the Bible

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.

he keeps his hand from [oppressing] the poor, does not receive interest or increase [from the needy], but executes My ordinances and walks in My statutes; he shall not die for the sin (guilt) of his father; he shall certainly live.

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.
