Jeremiah 21:7

Afterward; after that many of the people of this city shall be destroyed, some by the enemy assaulting and skirmishing with them; others by the famine that shall be amongst them through a want of victuals, being all spent with the long siege; others by the pestilence. Zedekiah, who shall escape these three judgments, together with his courtiers, and the residue of the people, shall be delivered into the power of the king of Babylon, and into the power of such as will not be content with the plunder of their houses, but thirst after their blood; and these enemies (set on by Nebuchadnezzar) shall smite them with the sword, without showing them any mercy or pity. This is not to be understood of king Zedekiah himself, for God let him know, Jeremiah 34:4, that he should not die by the sword, but in peace, as he did afterward in Babylon, though in prison; but it was true of his sons and courtiers, and a great part of the people, Jeremiah 49:6,8 Jeremiah 52:10. Those who went into captivity were only such as had revolted during the siege, and many of those that were of the poor of the land, for the rest there was little pity had of them, or mercy showed to them, as may be seen, Jer 39, Jer 52 2 Chronicles 36:17.
