Genesis 42:24

He turned himself and wept tears, partly of natural affection and compassion towards his brethren, now in great distress and anguish; and partly of joy, to see the happy success of his design and rigorous carriage, in bringing them to the sight of their sins. He chooseth to punish Simeon, partly, because next to Reuben he was the eldest, and, as it may be probably gathered from his bloody disposition, Genesis 34:25, Genesis 49:6, the most fierce and forward against Joseph, when Reuben was for milder counsels, as we see here, Genesis 42:22, Genesis 38:29; and partly, because the detainment of one of so perverse and furious a temper would least afflict his father, and most secure Benjamin, who was to come with his brethren. He bound him before their eyes, that it might make deeper impression upon their hard hearts, and make their repentance more effectual.
