Genesis 37:21

Reuben, who was the eldest son, and therefore specially responsible for his younger brother, opposed this murderous proposal. He dissuaded his brethren from killing Joseph (נפשׁ פ הכּה ), and advised them to throw him "into this pit in the desert," i.e., into a dry pit that was near. As Joseph would inevitably perish even in that pit, their malice was satisfied; but Reuben intended to take Joseph out again, and restore him to his father. As soon, therefore, as Joseph arrived, they took off his coat with sleeves and threw him into the pit, which happened to be dry.

At this chapter begins the story of Joseph, who, in every subsequent chapter but one to the end of this book, makes the greatest figure. He was Jacob's eldest son by his beloved wife Rachel, born, as many eminent men were, of a mother that had been long barren. His story is so remarkably divided between his humiliation and his exaltation that we cannot avoid seeing something of Christ in it, who was first humbled and then exalted, and, in many instances, so as to answer the type of Joseph. It also shows the lot of Christians, who must through many tribulations enter into the kingdom. In this chapter we have, I. The malice his brethren bore against him. They hated him, 1. Because he informed his father of their wickedness (Gen 37:1, Gen 37:2). 2. Because his father loved him (Gen 37:3, Gen 37:4). 3. Because he dreamed of his dominion over them (Gen 37:5-11). II. The mischiefs his brethren designed and did to him. 1. The kind visit he made them gave an opportunity (Gen 37:12-17). 2. They designed to slay him, but determined to starve him (Gen 37:18-24). 3. They changed their purpose, and sold him for a slave (Gen 37:25-28). 4. They made their father believe that he was torn in pieces (Gen 37:29-35). 5. He was sold into Egypt to Potiphar (Gen 37:36). And all this was working together for good.

37:21-24 Reuben was perhaps trying to get back into his father’s good graces (35:22) by exercising the leadership of the firstborn (cp. 42:22). Reuben succeeded in saving Joseph’s life, but he failed to earn his father’s favor (37:29-30).
