Genesis 47:16

Joseph said, Give your cattle— There was certainly no injustice, as Chandler in his Vindication observes, in making the AEgyptians pay for the corn, which Joseph had bought with Pharaoh's money, and laid up with great care and expence: and in demanding their cattle, he had, most probably, a view to save them; for, as they had not corn for themselves, they could much less have it for their cattle; and therefore this was the only way to preserve the lives of both, and to prevent that waste of the corn which must have been made if they had had the keeping and feeding of the cattle themselves: and it is highly probable, that he returned them their cattle after the famine, when they were fixed again in their several habitations, otherwise it would have been hardly possible for them to support their families, and carry on their business.
