Psalm 15:5
He who does not put out his money for interest [to one of his own people], and who will not take a bribe against the innocent. He who does these things shall never be moved. [Exodus 22:25-26].
“Israel was originally not a mercantile people, and the law aimed at an equal diffusion of wealth, not at enriching some while others were poor.
The spirit of the law is still obligatory, not to take advantage of a brother’s distress to lend at interest ruinous to him; but the letter of the law is abrogated, and a loan at moderate interest is often of great service to the poor.
Hence, it is referred to by our Lord in parables, apparently as a lawful as well as recognized usage. [Matthew 25:27; Luke 19:23].” – Fausset’s Bible Encyclopedia and Dictionary.
