Charles Ellicott Commentary Exodus 22:25

"If thou lend money to any of my people with thee that is poor, thou shalt not be to him as a creditor; neither shall ye lay upon him interest." — Exodus 22:25 (ASV)

Usurer... usury. —The Hebrew nûsheh and nĕshek have no sense of “excess” attached to them. They mean simply “interest,” and “ the man who lends upon interest.”
