1. Mose 42:18

On the third day Joseph modified his severity. "This do and live," i.e., then ye shall live: "I fear God." One shall remain in prison, but let the rest of you take home "corn for the famine of your families," and fetch your youngest brother, that your words may be verified, and ye may not die, i.e., may not suffer the death that spies deserve. That he might not present the appearance of despotic caprice and tyranny by too great severity, and so render his brethren obdurate, Joseph stated as the reason for his new decision, that he feared God. From the fear of God, he, the lord of Egypt, would not punish or slay these strangers upon mere suspicion, but would judge them justly. How differently had they acted towards their brother! The ruler of all Egypt had compassion on their families who were in Canaan suffering from hunger; but they had intended to leave their brother in the pit to starve! These and similar thoughts could hardly fail to pass involuntarily through their minds at Joseph's words, and to lead them to a penitential acknowledgement of their sin and unrighteousness. The notion that Joseph altered his first intention merely from regard to his much afflicted father, appears improbable, for the simple reason, that he can only have given utterance to the threat that he should keep them all in prison till one of them had gone and fetched Benjamin, for the purpose of giving the greater force to his accusation, that they were spies. But as he was not serious in making this charge, he could not for a moment have thought of actually carrying out the threat. "And they did so:" in these words the writer anticipates the result of the colloquy which ensued, and which is more fully narrated afterwards. Joseph's intention was fulfilled. The brothers now saw in what had happ…

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.).

42:18-20 Rather than keep all but one, Joseph would release all but one to take grain home to their starving families.
