Commentary on the Book of Joshua John Calvin
JOHN CALVIN
that Joshua furnished a new ambuscade, as if the number, already excessive, were not sufficient, but that the writer now merely shows how the thirty-five thousand whom Joshua had armed were distributed. For to what end would so small a reinforcement have been given to so great a multitude? Besides, the place where they are ordered to halt is the same as that which had been previously pointed out; this could not apply to two separate bodies of troops.
15. And Joshua and all Israel made as if they were beaten, etc This is another stratagem. By pretending flight they draw off the enemy to a distance, leaving them no retreat afterwards into the city, which was in flames before they suspected that any disaster was to be apprehended in their rear. Hence, while the king of Ai pursues the Israelites as vanquished, the part of the army which lay hid towards Bethel had sufficient time to take the city, and make it too late for the inhabitants to perceive that they were utterly undone. For after they had been already repulsed, and were everywhere slaughtered, they were overwhelmed with despair on beholding the flames of the city, and so completely surrounded that not an individual could escape.
The question here asked by some, as to whether it is lawful to overcome an enemy by wiles and stratagem, originates in gross ignorance. First, it is certain that wars are carried on not merely by striking blows; for those are considered the best commanders who accomplish more by art and counsel than by mere violence; and secondly, the longer any one has served so as to acquire experience, the better soldier he makes. If war, then, is lawful, it is beyond all controversy that the usual methods of conquering may be lawfully employed, provided always that there be no violation of faith once pledged either by truce or in any other way.
17. And there was not a man left in Ai, etc It will be clear from the context that some were taken in the city and slain, and therefore we must hold that the sally was not by all universally, and that the old men and women and many others unfit for war, did not rush forth into the fields; the meaning simply is, that no garrison was left to defend the city. The same thing is said of Bethel, and hence we may easily conjecture that Bethel, as it was a small unimportant town, belonged to another power. The inhabitants, however, from being unable to defend their own city, abandoned it, and offered their whole force to the king of Ai, to whom they were perhaps tributaries. It is uncertain whether they went to the king of Ai before the arrival of the Israelites, to unite their forces with his in the contest, but the probability is, that as they were unable to resist they had come by agreement into a fortified and more populous city. They thought that they could not, possibly be safe unless they were preserved under the shadow of a neighboring city superior to their own.
18. And the Lord said unto Joshua, etc This passage shows, that owing either to the strong fortifications of the city, or the valor of its inhabitants, or
