John Gill Bible Commentary

Ye have multiplied your slain in this city,.... Had killed many of the prophets of the Lord that had been sent unto them, and had shed much innocent blood; and not only had unjustly condemned many to die, and had put them to death without a cause; but also the death of all those that were slain while the city was besieging, and when it was taken, were owing to their advice and counsel, in encouraging them to hold out, and not deliver up the city; fancying they should be able to defend it, contrary to the declarations of the Lord by the prophet; wherefore their death is laid to such advisers, and they are called their slain: and ye have filled the streets thereof with the slain; such numbers of innocent persons being put to death, as in the times of Manasseh, Kg2 21:16; or so many dying of the famine, pestilence, and sword, during the siege, and at the taking of Jerusalem.
