17. And he put them altogether into ward. Here, not by words only, as before, but by the act itself, Joseph shows himself severe towards his brethren, when he shuts them all up in prison, as if about to bring them to punishment: and during three days torments them with fear. We said a little while ago, that from this act no rule for acting severely and rigidly is to be drawn; because it is doubtful whether he acted rightly or otherwise. Again, it is to be feared lest they who plead his example should be far removed from his mildness, and that they should prove to be rather his apes than his true imitators. Meanwhile, it plainly appears what he was aiming at; for he does not mitigate their punishment, as if at the end of three days he was appeased; but he renders them more anxious about the redemption of their brother, whom he retains as a hostage. Lest, however, immoderate fear should deter them from returning, he promises to act with good faith towards them: and to convince them of that, he declares that he fears God, which expression is worthy of observation. Doubtless he speaks from the inward feeling of his heart, when he declares that he will deal well and truly with them, because he fears God. Therefore the commencement and the fountain of that good and honest conscience, whereby we cultivate fidelity and justice towards men, is the fear of God. There appears indeed some probity in the despisers of God; but it soon goes off in smoke, unless the depraved affections of the flesh are restrained as with a bridle, by the thought that God is to be feared, because he will be the Judge of the world. For whoever does not think that he must render an account, will never so cultivate integrity as to refrain from pursuing what he supposes will be useful to himself. Wherefore, if we wish to be free from perfidy, craft, cruelty, and all wicked desire of doing injure, we must labor earnestly that religion may flourish among us. For whenever we act with want of sincerity or humanity towards each other, impiety openly betrays itself. For whatever there is of rectitude or justice in the world, Joseph comprised in this short sentence, when he said, that he feared God.
