"He who oppresses the poor blasphemes his Maker, but he who is kind to the needy glorifies him." (Proverbs 14:31)
"He who oppresses the poor to enrich himself will yield up his gains to the rich as sheer loss. Injure not the poor because they are poor, nor crush the needy at the gate; For the LORD will defend their cause, and will plunder the lives of those who plunder them. Open your mouth in behalf of the dumb, and for the rights of the destitute; Open your mouth, decree what is just, defend the needy and the poor!" (Proverbs 14:31, 22:16, 22-3, 31:8-9")
"Woe to those who make unjust laws, to those who issue oppressive decrees, to deprive the poor of their rights and withhold justice from the oppressed of my people, making widows their prey and robbing the fatherless. What will you do on the day of reckoning, when disaster comes from afar? To whom will you run for help? Where will you leave your riches?" (Isaiah 10:1-3)
"The scoundrel's methods are wicked, he makes up evil schemes to destroy the poor with lies, even when the plea of the needy is just. But the noble man makes noble plans, and by noble deeds he stands." (Isaiah 32:7,8)
"Yet on the day of your fasting, you do as you please and exploit all your workers....Is not this the kind of fasting I have chosen: to loose the chains of injustice and untie the cords of the yoke, to set the oppressed free and break every yoke? Is it not to share your food with the hungry and to provide the poor wanderer with shelter- when you see the naked, to clothe him, and not to turn away from your own flesh and blood?'" (Isaiah 58:3,6,7,10)
