37:26 What profit is it if we slay our brother? - It will be less guilt and more gain to sell him. They all agreed to this. And as Joseph was sold by the contrivance of Judah for twenty pieces of silver, so was our Lord Jesus for thirty, and by one of the same name too, Judas. Reuben it seems, was gone away from his brethren when they sold Joseph, intending to come round some other way to the pit, and to help Joseph out of it. But had this taken effect, what had become of God's purpose concerning his preferment, in Egypt? There are many devices of the enemies of God's people to destroy them, and of their friends to help them, which perhaps are both disappointed, as these here; but the counsel of the Lord that shall stand. Reuben thought himself undone because the child was sold; I, whither shall I go? He being the eldest, his father would expect from him an account of him; but it proved they had all been undone, if he had not been sold.
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.
