Jeremiah 50:33
Thus saith the LORD of hosts; The children of Israel and the children of Judah were oppressed together: and all that took them captives held them fast; they refused to let them go. Thus saith the LORD of hosts; The children of Israel and the children of Judah were oppressed together: and all that took them captives held them fast; they refused to let them go.
The children of Israel and the children of Judah were brought into oppression together while in captivity. Those who had taken them captive kept a firm grip upon them and held them fast. Their captors refused to release them and would not let them go.
Their Redeemer is strong, even the Lord of hosts, and He will plead their cause. By pleading their cause He will bring rest to the land. That same intervention will bring distress upon Babylon.
