My son, despise not the chastening of the Lord,.... This seems to be introduced to prevent an objection that may be made to the above promise of plenty; seeing the children of God are often afflicted in this world; even the wise and pious, and those that fear the Lord, and honour him; which is accounted for, and the reason of it given, in Pr 3:12.
These words are cited in Heb 12:5, and are represented as an exhortation, spoken unto children, the children of God; by which it appears, that not any single person is meant by "my son"; and, as not here, so neither elsewhere in this book, where the same phrase is used.
