- NKJV Deu 23:19"You shall not charge interest to your brother--interest on money [or] food [or] anything that is lent out at interest.
- KJV Due 23:19Thou shalt not lend upon usury to thy brother; usury of money, usury of victuals, usury of any thing that is lent upon usury
I would like to ask what the definition of the word "usury" is in the Old Testament law. Was it wrong to charge any interest at all, or only wrong to charge excessive interest?
It is indeed wrong to charge any interest at all, two consequences seem to follow because men subjecitvely value present goods higher than future goods. (1) The investment and the accumulation of capital goods is hindered. The reason is that one has a choice between using any given resource for present consumption or, by savings, for the production of captial goods. The experience of the last few hundred years, demonstrates the wellbeing of the comon man is greatly benefited by the accumulation of capitial goods (i.e. we live in a state of wealth compared to those of ancient times due to savings). If the benefits of savings are diminished by the fact that no interest can be recieved, then some people will engage in more present consumption than otherwise, at the expense of loss the ability to produce the things people need (and would otherwise have preferred to have) in the future. (2) Those who have some wealth have the ability to either lend the money, or use it for consumption. If the ability to recieve interest on a loan is removed, one who might otherwise have lent a sum to one in need, in a mutually beneficial arrangement, would be more inclinded to never make the loan at all and use the money for some other purpose. These "unintended consquenses" are not evil, but they are perplexing. The would be resolved if it were the case that a market rate of interest is legal to charge.
