The Mosaic law encouraged the practice of lending (Deuteronomy 15:7; Psalms 37:26; Matthew 5:42); but it forbade the exaction of interest, except from foreigners.
Usury was strongly condemned (Proverbs 28:8; Ezek. 18:8, 13, 17; 22:12; Psalms 15:5).
On the Sabbatical year all pecuniary obligations were cancelled (Deuteronomy 15:1-11). These regulations prevented the accumulation of debt.
