If thou lend money to any of my people that is poor by thee, thou shalt not be to him as an usurer, neither shalt thou lay upon him usury.

Wesley's Notes

22:25 If thou lend - They must not receive use for money from any that borrowed for necessity. And such provision the law made for the preserving estates to their families by the year of Jubilee, that a people who had little concern in trade could not be supposed to borrow money but for necessity; therefore it was generally forbidden among themselves; but to a stranger they were allowed to lend upon usury. This law therefore in the strictness of it seems to have been peculiar to the Jewish state; but in the equity of it, it obligeth us to shew mercy to those we have advantage against, and to be content to share with those we lend to in loss as well as profit, if Providence cross them: and upon this condition it seems as lawful to receive interest for my money, which another takes pains with, and improves, as it is to receive rent for my land, which another takes pains with, and improves, for his own use. They must not take a poor man's bed - clothes in pawn; but if they did, must restore them by bed - time.

Matthew Henry's Concise Commentary

22; 1 - 31 Judicial laws. - The people of God should ever be ready to show mildness and mercy, according to the spirit of these laws. We must answer to God, not only for what we do maliciously, but for what we do heedlessly. Therefore, when we have done harm to our neighbour, we should make restitution, though not compelled by law. Let these scriptures lead our souls to remember, that if the grace of God has indeed appeared to us, then it has taught us, and enabled us so to conduct ourselves by its holy power, that denying ungodliness and wordly lusts, we should live soberly, righteously, and godly in this present world, Titus 2:12. And the grace of God teaches us, that as the Lord is our portion, there is enough in him to satisfy all the desires of our souls.
