And Reuben spake unto his father, saying, Slay my two sons, if I bring him not to thee: deliver him into my hand, and I will bring him to thee again.

Jamieson-Fausset-Brown Bible Commentary

37. Reuben spake, . Slay my two sons, if I bring him not to thee-This was a thoughtless and unwarrantable condition-one that he never seriously expected his father would accept. It was designed only to give assurance of the greatest care being taken of Benjamin. But unforeseen circumstances might arise to render it impossible for all of them to preserve that young lad (Jas 4:13), and Jacob was much pained by the prospect. Little did he know that God was dealing with him severely, but in kindness (Heb 12:7, 8), and that all those things he thought against Him were working together for his good.

Matthew Henry's Concise Commentary

42:29-38 Here is the report Jacob's sons made to their father. It troubled the good man. Even the bundles of money Joseph returned, in kindness, to his father, frightened him. He laid the fault upon his sons; knowing them, he feared they had provoked the Egyptians, and wrongfully brought home their money. Jacob plainly distrusted his sons, remembering that he never saw Joseph since he had been with them. It is bad with a family, when children behave so ill that their parents know not how to trust them. Jacob gives up Joseph for gone, and Simeon and Benjamin as in danger; and concludes, All these things are against me. It proved otherwise, that all these things were for him, were working together for his good, and the good of his family. We often think that to be against us, which is really for us. We are afflicted in body, estate, name, and in our relations; and think all these things are against us, whereas they are really working for us a weight of glory. Thus does the Lord Jesus conceal himself and his favour, thus he rebukes and chastens those for whom he has purposes of love. By sharp corrections and humbling convictions he will break the stoutness and mar the pride of the heart, and bring to true repentance. Yet before sinners fully know him, or taste that he is gracious, he consults their good, and sustains their souls, to wait for him. May we do thus, never yielding to discouragement, determining to seek no other refuge, and humbling ourselves more and more under his mighty hand. In due time he will answer our petitions, and do for us more than we can expect.
