Jeremiah 21:8-9

And to this people you [Jeremiah] shall say, Thus says the Lord: Behold, I set before you the way of life and the way of death. He who remains in this city [Jerusalem] shall die by the sword and by famine and by pestilence. But he who goes out and passes over to the Chaldeans who besiege you, he shall live, and his life shall be to him his only booty [as a prize of war].
