Matthew Poole and continuators on Ezekiel 31:17

17 They also went down into hell with him, unto them that be slain with the sword; and they that were his arm, that dwelt under his shadow in the midst of the heathen.

Either his neighbour Kings and Princes, or those that were his own Subjects, but rich and mighty.

Were broken and perisht with him, and went to those God had slain for their pride and wickedness.

His loyal and faithful Subjects and Friends abroad, who having been protected by him, remembred it, and adhered to him to support him; but all fell, are extinct, and gone down to the pit, where many proud, but no pride; where all know themselves dust and ashes, and God glorious, holy and just.
