Exodus 22:21-25

“Do not mistreat or oppress a foreigner, for you were foreigners in Egypt. “Do not take advantage of the widow or the fatherless. If you do and they cry out to me, I will certainly hear their cry. My anger will be aroused, and I will kill you with the sword; your wives will become widows and your children fatherless. “If you lend money to one of my people among you who is needy, do not treat it like a business deal; charge no interest.
