Exodus 22:21-27 - Regulations Regarding Foreigners And The Poor
21 Thou shalt neither mistreat a stranger nor oppress him; for ye were strangers in the land of Egypt. 22 Ye shall not afflict any widow or fatherless child. 23 If thou afflict them in any manner, and they cry at all unto me, I will surely hear their cry; 24 and my wrath shall wax hot, and I will kill you with the sword; and your wives shall be widows, and your children fatherless.
25 If thou should lend money to my people, to the poor who is with thee, thou shalt not be to him as a usurer, neither shalt thou lay upon him usury.
26 If thou at all take thy neighbour's clothing as a pledge, thou shalt deliver it unto him before the sun goes down; 27 for only that is his covering, it is his clothing to cover his flesh, in which he must sleep; and it shall come to pass, when he cries unto me, that I will hear, for I am merciful.
