And stay you not, [but] pursue after your enemies
That is, do not stay at this cave, but having placed a sufficient guard there, go in pursuit of the enemy, with as much celerity as possible:
and smite the hindmost of them;
their rear; or "tail" them F15, as the word is, cut off the tail of them:
suffer them not to enter their cities;
where they would not only be safe themselves for a while, but would be able to hold out against a siege for some time, and give much trouble to conquer them:
for the Lord your God hath delivered them into your hands;
this he said to encourage them, and quicken them to the pursuit of them with all eagerness and vehemence. According to the Samaritan Chronicle F16, the signal or watchword was,
``God is strong in battle, God is his name.''
