Ezekiel 18:8, 13

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.
