15. And it came to pass on the seventh day, etc Here, also, God seemed, by leading the people so often round the city, not only to keep the matter in suspense, but purposely to sport with the miseries of the people, who were fatiguing themselves to no purpose. For why does he not order them suddenly to attack the city? Why does he keep them in their former silence, even to weariness, and not open their mouths to shout? But the happy fruit of this endurance teaches us, that there is nothing better than to leave the decisive moments and opportunities of acting at his disposal, and not, by our haste, anticipate his providence, in which, if we acquiesce not, we obstruct the course of his agency. Therefore, while the priests were sounding, God ordered a corresponding shout to be raised by the people, that in this way he might prove that he is not pleased with any impetuosity which men manifest at their own hands, but above all things requires a regulated zeal, of which the only rule is not to move either tongue, or feet, or hands, till he order. Here, the rams’ horns undoubtedly represented his authority.
