Genesis 42:4 Meaning and Commentary

Genesis 42:4

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.

Genesis 42:4 In-Context

2 “Look,” he added, “I have heard that there is grain in Egypt. Go down there and buy some for us, so that we may live and not die.”

3 So ten of Joseph’s brothers went down to buy grain from Egypt.

4 But Jacob did not send Joseph’s brother Benjamin with his brothers, for he said, “I am afraid that harm might befall him.”

5 So the sons of Israel were among those who came to buy grain, since the famine had also spread to the land of Canaan.

6 Now Joseph was the ruler of the land; he was the one who sold grain to all its people. So when his brothers arrived, they bowed down before him with their faces to the ground.
