'Oppressor' in the Bible

O house of David, thus said Jehovah: Decide ye judgment at morning, And deliver the plundered from the hand of the oppressor, Lest My fury go forth as fire, And hath burned, and none is quenching, Because of the evil of your doings.

Thus said Jehovah: Do ye judgment and righteousness, And deliver the plundered from the hand of the oppressor, And sojourner, orphan, and widow, ye do not oppress nor wrong, And innocent blood ye do not shed in this place.
