| Gill's Exposition of the Entire Bible Hear counsel, and receive instruction,.... Of parents, masters, and ministers; especially the counsel and instruction of Wisdom, of Jesus Christ, the Wisdom of God, the wonderful Counsellor; and of his Gospel and of the Scriptures, which are able to make a man wise unto salvation; that thou mayest be wise in thy latter end; in the latter end of life, at death; that then it may appear a man has been so wise as to be concerned for a future state, for the good of his soul in another world; by listening to the counsel and instruction of Christ, in his word; by looking to him, and believing in him, for life and salvation; by leaning and living upon him; and committing the affairs of his soul, and the salvation of it, to him.
Keil and Delitzsch Biblical Commentary on the Old Testament20 Hearken to counsel, and receive instruction, That thou mayest become wise afterwards. The rule of morals, Proverbs 12:15, receives here the paraenetic tone which is the keynote of the introduction chap. 1-9. Lwenstein translates: that thou mayest finally become wise. But בּאחריתך corresponds rather to our "hinfort" [posthac] than to "endlich" [finally]. He to whom the warning is directed must break with the self-willed, undisciplined ראשׁית beginning of his life, and for the future (τὸν ἐπίλοιπον ἐν σαρκὶ χρόνον, 1 Peter 4:2) become wise. The relative contrast between the two periods of life is the same as at Job 8:7.

It is far better to have a heart to do good, and want ability for it, than to have ability for it, and want a heart to it. 23. Those that live in the fear of God, shall get safety, satisfaction, and true and complete happiness. 24.
