37:23-30 They threw Joseph into a pit, to perish there with hunger and cold; so cruel were their tender mercies. They slighted him when he was in distress, and were not grieved for the affliction of Joseph, see Am 6:6; for when he was pining in the pit, they sat down to eat bread. They felt no remorse of conscience for the sin. But the wrath of man shall praise God, and the remainder of wrath he will restrain, Ps 76:10. Joseph's brethren were wonderfully restrained from murdering him, and their selling him as wonderfully turned to God's praise.

His intentions were excellent, and his feelings no doubt painfully lacerated when he discovered what had been done in his absence. But the thing was of God, who had designed that Joseph's deliverance should be accomplished by other means than his.
