Psalms 37:26

There is money lent out at interest, and there is money lent in kindness. But the Lord expects a return. Money gets interest paid in cash. The grace of kindness wins an increase of faith. Lend out your faith generously to the Gentiles, and your grace will be multiplied. Do not go about borrowing like a pauper. Act like someone really rich and lend out so as to make great profit. Peter lent; Paul lent; John the Evangelist lent; and certainly they were not in want. What they lent was Christ's money; they were not charging high rates of interest. So lend and do not grow weary.

"He is always merciful, and lendeth." "Foeneratur" is used in Latin indeed, both for him who lendeth, and for him who borroweth. But in this passage the meaning is more plain, if we express it by "foenerat." What matters it to us, what the grammarians please to rule? It were better for us to be guilty of a barbarism, so that ye understand, than that in our propriety of speech ye be left unprovided. Therefore, that "righteous man is all day merciful, and (foenerat) lendeth." Let not the lenders of money on usury, however, rejoice. For we find it is a particular kind of lender that is spoken of, as it was a particular kind of bread; that we may, in all passages, "remove the roof," and find our way to Christ. I would not have you be lenders of money on usury; and I would not have you be such for this reason, because God would not have you. ...Whence does it appear that God would not have it so? It is said in another place, "He that putteth not out his money to usury." And how detestable, odious, and execrable a thing it is, I believe that even usurers themselves know. Again, on the other hand, I myself, nay rather our God Himself bids thee be an usurer, and says to thee, "Lend unto God." If thou lendest to man, hast thou hope? and shalt thou not have hope, if thou lendest to God? If thou hast lent thy money on usury to man, that is, if thou hast given the loan of thy money to one, from whom thou dost expect to receive something more than thou hast given, not in money only, but anything, whether it be wheat, or wine, or oil, or whatever else you please, if you expect to receive more than you have given, you are an usurer, and in this particular are not deserving of praise, but of censure. "What then," you say, "am I to do, that I may 'lend' profitably?" Consider what the usurer does. […]

Then when he says, "I was young," he shows by experience that the goods of the just are fruitful, but not those of the wicked. And he sets forth this long experience regarding two things. First, regarding the immunity of the good from evils. Second, …

He is ever merciful, and lendeth,....

He is ever merciful, and lendeth. The righteous are constantly under generous impulses; they do not prosper through parsimony, but through bounty. Like the bounteous giver of all good, of whom they are the beloved sons, they delight in doing good. How stingy covetous professors can hope for salvation is a marvel to those who read such verses as this in the Bible. And his seed is blessed. God pays back with interest in the next generation.
