Matthew Henry on Ruth 4:9-12

Men are ready to seize opportunities for increasing their estates, but few know the value of godliness. Such are the wise men of this world, whom the Lord charges with folly. They attend not to the concerns of their souls, but reject the salvation of Christ, for fear of marring their inheritance. But God did Boaz the honour to bring him into the line of the Messiah, while the kinsman, who was afraid of lessening himself, and marring his inheritance, has his name, family, and inheritance forgotten.
