Exodus 22:21-24

“You shall not wrong a sojourner or oppress him, for you were sojourners in the land of Egypt. You shall not mistreat any widow or fatherless child. If you do mistreat them, and they cry out to me, I will surely hear their cry, and my wrath will burn, and I will kill you with the sword, and your wives shall become widows and your children fatherless.
