The Midianites were greatly afraid of Simon, and, terrified and abashed, they spake to the sons of Jacob with little courage: "Said ye not that ye cast this lad into the pit because he was of a rebellious spirit? What, now, will ye do with an insubordinate slave? Rather sell him to us, we are ready to pay any price you desire." This speech was part of the purpose of God.
He had put it into the heart of the Midianites to insist upon possessing Joseph, that he might not remain with his brethren, and be slain by them. The brethren assented, and Joseph was sold as a slave while they sat over their meal. God spake, saying: "Over a meal did ye sell your brother, and thus shall Ahasuerus sell your descendants to Haman over a meal, and because ye have sold Joseph to be a slave, therefore shall ye say year after year, Slaves were we unto Pharaoh in Egypt."
