Isa 49:25-26

25But thus says the Lord: Even the captives of the mighty shall be taken, and the prey of the tyrant be rescued; for I will contend with those who contend with you, and I will save your children.26I will make your oppressors eat their own flesh, and they shall be drunk with their own blood as with wine. Then all flesh shall know that I am the Lord your Savior, and your Redeemer, the Mighty One of Jacob.
