Exodus 22:22-24
22:22 “You must not afflict any widow or orphan.
22:23 If you afflict them in any way and they cry to me, I will surely hear their cry,
22:24 and my anger will burn and I will kill you with the sword, and your wives will be widows and your children will be fatherless.
Psalms 140:12
140:12 I know that the Lord defends the cause of the oppressed
and vindicates the poor.
