He sent a man before them, even Joseph, who was sold for a servant:
Read Chapter 105
Augustine of Hippo
AD 430
11. "But He had sent a man before them" (ver. 17). What man? "Even Joseph." How did He send him? "Joseph was sold to be a bond-servant." When this happened, it was the sin of his brethren, and, nevertheless, God sent Joseph into Egypt. We should therefore medirate on this important and necessary subject, how God useth well the evil works of men, as they on the other hand use ill the good works of God.
He sent. Drawing good from the malice of Joseph's brethren, (Haydock) in which he had no hand. (Berthier)
Who could have thought that this event would have tended to Joseph's exaltation, and to the safety of his father's house?
