Jeremiah 21:9

But certainly, if ever any man spake high treason, this prophet now did it, when there was an enemy besieging them, telling them, that if they would save their lives, they must revolt from their king, and join with their enemies. All that can be said in excuse for the prophet is, that this was a Divine revelation to him, and a message sent to the king himself. His life shall be given him for a prey, appeareth to have been a proverbial expression, either signifying.

1. A man's possession of his life, as a prey or booty recovered from death, or the hand of the enemy; or,

2. A man's rejoicing in the saving of his life, as if he had got some notable booty.
