Scripture uses the term interest in its general sense of a charge levied upon a debt or for use of the creditor's money or other possessions. While Israelites were permitted to charge foreigners interest (Deuteronomy 23:19-20), they were not to charge each other interest since it was considered exploitation of a fellow Israelite's misfortune (Leviticus 25:35-37; cf. Nehemiah 5:7, 10). Jesus gave implied approval of investment with a financial institution to earn interest (Matthew 25:27). However, He taught that the ultimate motive in a private loan should be love and goodness rather than expecting to collect interest on the loan (Luke 6:32-35).
