Joshua 10:24

Put your feet upon the necks of these kings: this he did not from pride and contempt of their dignity in itself; but, partly, as a punishment of their impious rebellion against their sovereign Lord; partly, in pursuance of that curse of servility due to all this people, Genesis 9:25; partly, as a token to assure his captains that God would subdue the proudest of them all under their feet; and partly, to oblige and teach his people severely to execute the judgment of God upon them, and not to spare any of them, either out of a foolish pity, or out of respect to their dignity, as Saul afterwards spared Agag to his own ruin.
