Exodus 22:21-27 - Regulations Regarding Foreigners And The Poor
21 And thou shall not wrong a sojourner, neither shall thou oppress him, for ye were sojourners in the land of Egypt. 22 Ye shall not afflict any widow, or fatherless child. 23 If thou afflict them at all, and they cry at all to me, I will surely hear their cry, 24 and my wrath shall grow hot, and I will kill you with the sword, and your wives shall be widows, and your sons fatherless.
25 If thou lend money to any of my people with thee who is poor, thou shall not be to him as a creditor, neither shall ye lay upon him interest.
26 If thou at all take thy neighbor's garment to pledge, thou shall restore it to him before the sun goes down, 27 for that is his only covering. It is his garment for his skin. How shall he sleep? And it shall come to pass, when he cries to me, that I will hear, for I am gracious.
