'Oppressor's' in the Bible

As a result, you have forgotten the LORD who made you, who stretched out the heavens and laid the earth's foundations, and you live in constant fear every day because of the oppressor's fury, since he's ready to destroy. Now where is the oppressor's fury?

They repeatedly stumble and fall. They say to each other, "Get up! Let's go back to our people and to the land of our birth, away from the oppressor's sword.'

Eliminate from Babylon the one who plants seeds and the one who uses the sickle at harvest time. Because of the oppressor's sword, let each one turn toward his own people and flee to his own land."
