What the Jewish people imparted to other nations, they did not take in return: instruction. However, the one to whom the Lord revealed His wealth bestowed this precious gift, so he could nourish the nations with the richness of his message and attain prominence among them; yet, he himself did not have authority over him.
How can the one who shows compassion and lends consistently find himself in want (Psalm 36:26)? What does it signify for a just man to charge interest? Not copper, iron, or lead, but rather silver purified in the furnace (Psalm 11:7) is what the just man offers at the Lord's table, distributing to those in need, giving generously to one, two, or even five mina, ensuring that there is always abundance, as noted in Luke 19:13. Yet, we have learned that charging interest is prohibited by the law; Moses states, "Thou shalt not lend upon usury" (Deuteronomy 23:19). There exist two forms of usury: one involves money, the other pertains to grace.

It is essential to differentiate between them, for it is written, "If you offer sacrifices correctly but divide wrongly, you have sinned; be still" (Genesis 4:7). Divide appropriately to avoid sin. Let Moses guide you in this, as he encouraged you to divide rightly, emulating Abel, who apportioned properly, and steering clear of the fate of Cain, the fratricide, who failed in this regard. The Holy Spirit, who is responsible for all these matters, distributes to each according to His will (1 Corinthians 12:11), instructs us in how to divide. He dispenses as He wishes, while you divide according to your own capacity and strength. Recognize when the law is addressing money and when it speaks of grace! The law instructs you, "You shall lend to many nations," implying that the Lord demands interest; however, the command states that you shall not lend (Deuteronomy 15:6). Interest can be applied to both money and grace—the Lord requires interest on both; interest on money is rendered in coins, while grace is recompensed through faith. Bestow faith upon the Gentiles with great abundance, ensuring that you receive a plentiful measure of grace, but do not act as a borrower in need; rather, lend freely like a generous benefactor. Peter lent, Paul lent, John the Evangelist lent, among others, and none of them lacked for anything. They offered what belonged to Christ, not seeking personal gain. Therefore, lend, and continue to lend! Listen to the Scripture’s words: "Every day he has mercy and lends" (Psalm 36:26). The righteous lend in daylight, while the greedy hoard in darkness, for grace is a reward bestowed in light, whereas miserliness is associated with darkness. Thus, the offspring of the generous lender will be blessed, carrying the promise of reward.
