Exodus 22:23

²¹  Thou shalt neither vex 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 wise, 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 lend money to any of my people that is poor by thee, thou shalt not be to him as an usurer, neither shalt thou lay upon him usury.
