'Oppression' in the Bible

They said, "If you send the Ark of the God of Israel back, don't send it empty, but rather be sure to send back to him a guilt offering. Then you will be healed and will know why his oppression has not been removed from you."

Behold, as your life was respected this day in my eyes, so let my life be respected in the eyes of Yahweh, and let him deliver me out of all oppression."
