Genesis 42:7

7.He made himself strange unto them. It may be asked for what purpose Joseph thus tormented his brethren with threats and with terror. For if he was actuated by a sense of the injury received from them, he cannot be acquitted of the desire of revenge. It is, however, probable, that he was impelled neither by anger nor a thirst of vengeance, but that he was induced by two just causes to act as he did. For he both desired to regain his brother Benjamin, and wished to ascertain, — as if by putting them to the torture, — what was in their mind, whether they repented or not; and, in short, what had been their course of life since he had seen them last. For, had he made himself known at the first interview, it was to be feared lest they, keeping their father out of sight, and wishing to cast a vail over the detestable wickedness which they had committed, should only increase it by a new crime. There lurked, also, a not unreasonable suspicion concerning his brother Benjamin, lest they should attempt something perfidious and cruel against him. It was therefore important that they should be more thoroughly sifted; so that Joseph, being fully informed of the state of his father’s house, might take his measures according to circumstances; and also, that previous to pardon, some punishment might be inflicted which would lead them more carefully to reflect upon the atrocity of their crime. For whereas he afterwards showed himself to be placable and humane; this did not arise from the fact, that his anger being assuaged, he became, by degrees, inclined to compassion; but rather, as Moses elsewhere subjoins, that he sought retirement, because he could no longer refrain himself; herein intimating at the same time, that Joseph had forcibly repressed his tears so long as he retained a severe aspect; and, therefore, that he had felt throughout the same affection of pity towards them. And it appears that a special impulse moved him to this whole course of action. For it was no common thing, that Joseph, beholding so many authors of his calamities, was neither angry nor changed in his manner, nor broke out into reproaches; but was composed both in his countenance and his speech, as if he had long meditated at leisure, respecting the course he would pursue. But it may be inquired again, whether his dissimulation, which was joined with a falsehood, is not to be blamed; for we know how pleasing integrity is to God, and how strictly he prohibits his own people from deceit and falsehoods. Whether God governed his servant by some special movement, to depart without fault, from the common rule of action, I know not; seeing that the faithful may sometimes piously do things which cannot lawfully be drawn into a precedent. Of this, however, in considering the acts of the holy fathers, we must always beware; lest they should lead us away from that law which the Lord prescribes to all in common. By the general command of God, we must all cultivate sincerity. That Joseph feigned something different from the truth, affords no pretext to excuse us if we attempt anything of the same kind. For, though a liberty granted by privilege would be pardoned, yet if any one, relying on a private example, does not scruple to subvert the law of God, so as to give himself license to do what is therein forbidden, he shall justly suffer the punishment of his audacity. And yet I do not think that we ought to be very anxious to excuse Joseph, because it is probable that he suffered something from human infirmity, which God forgave him; for by Divine mercy alone could that dissimulation, which in itself was not without fault, escape condemnation.
