Exodus 22:25 “If you lend money to any of my people with you who is poor, you shall not be like a moneylender to him, and you shall not exact interest from him. If ever you take your neighbor’s cloak in pledge, you shall return it to him before the sun goes down, for that is his only covering, and it is his cloak for his body; in what else shall he sleep? And if he cries to me, I will hear, for I am compassionate.
Leviticus 25:35-37 “If your brother becomes poor and cannot maintain himself with you, you shall support him as though he were a stranger and a sojourner, and he shall live with you. Take no interest from him or profit, but fear your God, that your brother may live beside you. You shall not lend him your money at interest, nor give him your food for profit.
Proverbs 28:8 Whoever multiplies his wealth by interest and profit gathers it for him who is generous to the poor.
Ezekiel 18:17 withholds his hand from iniquity, takes no interest or profit, obeys my rules, and walks in my statutes
Interest was prohibited on loans made to the poor and the taking of collateral had to be reasonable. “The reason for the prohibition is presumably that the poor man borrows in his need. The loan is seen as assistance to a neighbor, and to make money from his need would be immoral.” (Guzik)
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. (Henry)
If a man should lend to one of the poor of his own people, he was not to oppress him by demanding interest; and if he gave his upper garment as a pledge, he was to give it him back towards sunset, because it was his only covering. God directs Himself at once to the hearts of the Israelites, and attacks the sins of selfishness and covetousness. (Keil)
When our hearts and minds begin to understand that all we have has been given to us by God, it is then when begin to understand the commands of God concerning the needs of others.
