Genesis 42:18 On the third day Joseph said to them, “Do this and you will live, for I fear God: if you are honest men, let one of your brothers remain confined where you are in custody, and let the rest go and carry grain for the famine of your households, and bring your youngest brother to me. So your words will be verified, and you shall not die.” And they did so. Then they said to one another, “In truth we are guilty concerning our brother, in that we saw the distress of his soul, when he begged us and we did not listen. That is why this distress has come upon us.” And Reuben answered them, “Did I not tell you not to sin against the boy? But you did not listen. So now there comes a reckoning for his blood.” They did not know that Joseph understood them, for there was an interpreter between them. Then he turned away from them and wept. And he returned to them and spoke to them. And he took Simeon from them and bound him before their eyes. And Joseph gave orders to fill their bags with grain, and to replace every man’s money in his sack, and to give them provisions for the journey. This was done for them.
Leviticus 25:43 You shall not rule over him ruthlessly but shall fear your God.
Nehemiah 5:9 So I said, “The thing that you are doing is not good. Ought you not to walk in the fear of our God
Luke 18:2 He said, “In a certain city there was a judge who neither feared God nor respected man.
Nehemiah 5:15 But I did not do so, because of the fear of God.
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 happened to them a divine retribution: “Surely we atone because of our brother, whose anguish of soul we saw, when he entreated us and we would not hear; therefore is this distress come upon us.” And Reuben reminded them how he had warned them to no purpose, not to sin against the boy – “and even his blood…behold it is required”; i.e., not merely the sin of casting him into the pit and then selling him, but his death also, of which we have been guilty through that sale. Thus they accused themselves in Joseph’s presence, not knowing that he could understand; “for the interpreter was between them.” Joseph had conversed with them through an interpreter, as an Egyptian who was ignorant of their language. “The interpreter,” viz., the one appointed for that purpose. But Joseph understood their words, and “turned away and wept”, with inward emotion at the wonderful leadings of divine grace, and at the change in his brothers’ feelings. He then turned to them again, and, continuing the conversation with them, had Simeon bound before their eyes, to be detained as a hostage (not Reuben, who had dissuaded them from killing Joseph, and had taken no part in the sale, but Simeon, the next in age). He then ordered his men to fill their sacks with corn, to give every one his money back in his sack, and to provide them with food for the journey. (Keil and Delitzsch )
It is most noteworthy to see Joseph feared God in the decisions he made, what he did, and what he said. In contrast, the minds of his brothers were seared with a hot iron in remembrance of how they treated Joseph. They had acted out of envy, jealousy, and without any fear of God.
Our lives are to be living sacrifices that humbly honor and glorify Jesus Christ in all that we think, say, and do. When we have this single purpose goal for our lives, it is then we will discern fleshly non-God honoring thoughts, actions, and words and be able to cast them out before they take root and cause harm to ourselves or others and more importantly dishonor God.
