'Oppression' in the Bible

In thee have they set light by father and mother: in the midst of thee have they dealt by oppression with the stranger: in thee have they vexed the fatherless and the widow.

The people of the land have used oppression, and exercised robbery, and have vexed the poor and needy: yea, they have oppressed the stranger wrongfully.

Moreover the prince shall not take of the people's inheritance by oppression, to thrust them out of their possession; but he shall give his sons inheritance out of his own possession: that my people be not scattered every man from his possession.
