There was not a city that made peace with the children of Israel, save the Hivites the inhabitants of Gibeon: they took all in battle.
To this objection, I answer, that the Israelites, though they were forbidden to show them any mercy, were met in a hostile manner, in order that the war might be just. And it was wonderfully arranged by the secret providence of God, that, being doomed to destruction, they should voluntarily offer themselves to it, and by provoking the Israelites be the cause of their own ruin. The Lord, therefore, besides ordering that pardon should be denied them, also incited them to blind fury, that no room might be left for mercy. And it behooved the people not to be too wise or prying in this matter. For while the Lord, on the one hand, interdicted them from entering into any covenant, and, on the other, was unwilling that they should take hostile measures without being provoked, a too anxious discussion of the procedure might have greatly unsettled their minds. Hence the only way of freeing themselves from perplexity was to lay their care on the bosom of God. And he in his incomprehensible wisdom provided that when the time for action arrived, his people should not be impeded in their course by any obstacle. Thus the kings beyond the Jordan, as they had been the first to take up arms, justly suffered the punishment of their temerity. For the Israelites did not assail them with hostile arms until they had been provoked. In the same way, also, the citizens of Jericho, by having shut their gates, were the first to declare war. The case is the same with the others, who, by their obstinacy, furnished the Israelites with a ground for prosecuting the war.
