'Oppression of the Poor' in the Bible

For the oppression of the poor, for the sighing of the needy, now will I arise, says the LORD; I will set him in safety from him that sneers at him.

If you see the oppression of the poor, and violent perverting of justice and righteousness in a province, marvel not at the matter: for the high official is watched by a higher one; and there are yet higher ones over them.
