Genesis 42:37

Reuben then offered his two sons to Jacob as pledges for Benjamin, if Jacob would entrust him to his care: Jacob might slay them, if he did not bring Benjamin back-the greatest and dearest offer that a son could make to a father. But Jacob refused to let him go. "If mischief befell him by the way, he would bring down my grey hairs with sorrow into Sheol" (cf. Gen 37:35).

We had, in the foregoing chapter, the fulfilling of the dreams which Joseph had interpreted: in this and the following chapters we have the fulfilling of the dreams which Joseph himself had dreamed, that his father's family should do homage to him. The story is very largely and particularly related of what passed between Joseph and his brethren, not only because it is an entertaining story, and probably was much talked of, both among the Israelites and among the Egyptians, but because it is very instructive, and it gave occasion for the removal of Jacob's family into Egypt, on which so many great events afterwards depended. We have, in this chapter, I. The humble application of Jacob's sons to Joseph to buy corn (Gen 42:1-6). II. The fright Joseph put them into, for their trial (Gen 42:7-20). III. The conviction they were now under of their sin concerning Joseph long before (Gen 42:21-24). IV. Their return to Canaan with corn, and the great distress their good father was in upon hearing the account of their expedition (Gen 42:25, etc.).

42:37 Reuben tried to take the lead; perhaps he thought he could get back into his father’s good favor (see 35:22), first by rescuing Joseph from certain death (37:21-22, 29-30) and now by keeping Benjamin safe.
