And let not thy soul spare for his crying. — Or, but set not thy soul on his destruction. Do not go so far as to kill him in thy zeal for his good, or despair of his amendment. (Comp. Ephesians 6:4; Colossians 3:21.) It may also signify “do not let him perish for want of chastisement,” as Proverbs 23:13 is also explained.
