Joshua tore his clothes, and fell to the earth on his face before the ark of Yahweh until the evening, he and the elders of Israel; and they put dust on their heads.
We are hence taught that saints, while they aim at the right mark, often stumble and fall, and that this sometimes happens even in their prayers, in which purity of faith and affections framed to obedience ought to be especially manifested. That Joshua felt particularly concerned for the divine glory, is apparent from the next verse, where he undertakes the maintenance of it, which had been in a manner assigned to him. What shall I say, he asks, when it will be objected that the people turned their backs? And he justly complains that he is left without an answer, as God had made him the witness and herald of his favor, whence there was ground to hope for an uninterrupted series of victories. Accordingly, after having in the loftiest terms extolled the divine omnipotence in fulfillment of the office committed to him, it had now become necessary for him, from the adverse course of events, to remain ignominiously silent. We thus see that nothing vexes him more than the disgrace brought upon his calling. He is not concerned for his own reputation, but fears lest the truth of God might be endangered in the eyes of the world. (71) In short, as it was only by the order of God that he had brought the people into the land of Canaan, he now in adversity calls upon him as author and avenger, just as if he had said, Since thou has brought me into these straits, and I am in danger of seeming to be a deceiver, it is for thee to interfere and supply me with the means of defense.
