Joshua 10:25

And Joshua said, rest not, nor be dismayed
Not meaning at the kings, who perhaps lay bound upon the ground, or however were not in a condition to make any resistance, so that they had nothing to fear from them; but this respects future time, and what other enemies they should meet with; who would be brought into subjection to them as these were, and therefore from hence should take heart:

be strong, and of good courage;
and go on valiantly in subduing the rest of their enemies, and not be afraid of them:

for thus shall the Lord do to all your enemies against whom ye fight;
put them into their hands, and give them power to tread on their necks: this shows that what Joshua did, or ordered to be done, was of the Lord.
