'Oppressor's' in the Bible

‘It shall come about on that day,’ says the Lord of hosts, ‘that I will break the yoke off your neck and I will tear off your bonds and force apart your shackles; and strangers will no longer make slaves of the people [of Israel].

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.'

Cut off the sower from Babylonas well as him who wields the sickle at harvest time.Because of the oppressor’s sword,each will turn to his own people,each will flee to his own land.
