Genesis 50:6

6. And Pharaoh said. We have seen that Joseph adopts a middle course. For he was not willing utterly to fail in his duty; yet, by catching at a pretext founded on the command of his father, he did not conduct himself with sufficient firmness. It is possible that Pharaoh was inclined, by the modesty of his manner, more easily to assent to his requests. Yet this cowardice is not, on this account, so sanctioned that the sons of God are at liberty to indulge themselves in it: for if they intrepidly follow where duty calls, the Lord will give the issue which is desired, beyond all expectation. For, although, humanly speaking, Joseph’s bland submission succeeded prosperously, it is nevertheless certain that the proud mind of the king was influenced by God to concede thus benignantly what had been desired. It is also to be observed, what great respect for an oath prevailed among blind unbelievers. For, though Pharaoh himself had not sworn, he still deemed it unlawful for him to violate, by his own authority, the pledge given by another. But at this day, reverence for God has become so far extinct, that men commonly regard it as a mere trifle to deceive, on one side or another, under the name of God. But such unbridled license, which even Pharaoh himself denounces, shall not escape the judgment of God with impunity.
