'Oppressions' in the Bible

"By reason of the multitude of oppressions they cry out. They cry for help by reason of the arm of the mighty.

Then I returned and saw all the oppressions that are done under the sun: and behold, the tears of those who were oppressed, and they had no comforter; and on the side of their oppressors there was power; but they had no comforter.

He who walks righteously, and speaks blamelessly; He who despises the gain of oppressions, who gestures with his hands, refusing to take a bribe, who stops his ears from hearing of blood, and shuts his eyes from looking at evil --

partly, being exposed to both reproaches and oppressions; and partly, becoming partakers with those who were treated so.
