Genesis 50:14

14.And Joseph returned. Although Joseph and the rest had left so many pledges in Egypt, that it would be necessary for them to return; it is yet probable that they were rather drawn back thither by the oracle of God. For God never permitted them to choose an abode at their own will; but as he had before led Abraham, Isaac, and Jacob in their journeying, so he held their sons shut up in the land of Goshen, as within barriers. And there is no doubt that the holy fathers left that oracle which we have in the fifteenth chapter and the thirteenth verse, Genesis 15:13 to their sons, to be kept in faithful custody as a precious treasure. (221) They return, therefore, into Egypt, not only because they were compelled by present necessity, but because it was not lawful for them to shake off with the hand, the yoke which God had put upon their necks. But if the Lord does not hold all men bound by voluntary obedience to himself, he nevertheless holds their minds by his secret rein, that they may not withdraw themselves from his government; nor can we form any other conjecture than that they were restrained by his fear, so that even when admonished of the tyrannical oppression which was coming upon them, they did not attempt to make their escape. We know that their disposition was not so mild as to prevent them from rebelling against lighter burdens. Wherefore, on this point, a special sense of religious obligation subdued them, so that they prepared themselves quietly and silently to endure the hardest servitude.
