He sent a man before them, even Joseph,.... Who, though but a lad of seventeen years of age when he was sold into Egypt, yet was a grown man when he stood before Pharaoh, and interpreted his dreams of plenty and famine to come; and advised him to lay up store in the years of plenty, against the years of famine; by which he appeared to be a wise man, as the Targum here calls him; see Ge 37:3.
Him God sent before into Egypt; before Jacob and his sons went down thither, to make provision for them, to support them in the time of famine, and preserve their lives. God is said to send him, though his brethren sold him out of envy; there being such a plain hand of Providence in this matter; and which is observed by Joseph himself over and over again, Ge 45:5, in which he was a type of Christ, in whom all provisions are made, and by whom they are communicated unto his people; who all receive out of his fulness, and grace for grace.
