Shall the prey be taken from the mighty, or the lawful captive delivered? But thus saith the LORD, Even the captives of the mighty shall be taken away, and the prey of the terrible shall be delivered: for I will contend with him that contendeth with thee, and I will save thy children. And I will feed them that oppress thee with their own flesh; and they shall be drunken with their own blood, as with sweet wine: and all flesh shall know that I the LORD am thy Saviour and thy Redeemer, the mighty One of Jacob.
If the captives in Babylon had any qualms as to the possibility of their being freed from their captor, they needed to know that Jehovah would contend with their adversaries and save their children. When the oppressors reaped what they had sown, then the world would know that the Lord is Israel’s Saviour and their Redeemer, the Mighty One of Jacob.
