Verse 4. - But (literally, and) Benjamin, Joseph's brother (vide Genesis 35:18), Jacob sent not with his brethren. Not because of his youth (Patrick, Lange), since he was now upwards of twenty years of age, but because he was Joseph's brother, and had taken Joseph's place in his father's affections (Lawson, Lange, Murphy, etc.), causing the old man to cherish him with tender solicitude. For he said (to, or within, himself, perhaps recalling the fate of Joseph), Lest peradventure mischief befall him. אָסון, from אָסַה, to hurt (Gesenius, Furst), and occurring only elsewhere in ver. 38, Genesis 44:29, and Exodus 21:22, 23, denotes any sort of personal injury in general, and in particular here such mischance as might happen to a traveler.

42:1-6 Jacob saw the corn his neighbours had bought in Egypt, and brought home. It is a spur to exertion to see others supplied. Shall others get food for their souls, and shall we starve while it is to be had? Having discovered where help is to be had, we should apply for it without delay, without shrinking from labour, or grudging expense, especially as regards our never-dying souls. There is provision in Christ; but we must come to him, and seek it from him.But Benjamin, Joseph's brother, Jacob sent not with his brethren,.... Benjamin is called Joseph's brother, because he was so both by father and mother's side, as the rest were not; him Jacob kept with him, being the youngest and his darling, the only son he had with him of his beloved wife Rachel; and was very probably the more beloved by him since he had been bereft of Joseph; and it was not only to keep him company that he retained him at home, but for the reason following:

for he said, lest peradventure mischief befall him; as had to Joseph his brother, as he imagined; either that the journey would be too much for him, being young, or lest he should be seized with sickness on the road, or rather with death, as Aben Ezra interprets it according to the Targums of Onkelos and Jonathan.
