Verse 16. - My reins shall rejoice. The "reins" (kelayoth), kidneys, are regarded as the seat of feeling and sensation (Job 19:27). or of the inner nature generally (Psalm 16:7; Revelation 2:22). I shall rejoice in my very soul when thy lips speak right things;i.e. when thy heart is so replete with wisdom, thy mind so well instructed as to utter naught but what is true and sensible (Proverbs 8:6). The composition of these two verses is noteworthy, 15a being parallel to 16b, and. 15b to 16a. Septuagint, "And thy lips shall linger in words (ἐνδιατρίψει λόγοις) with my lips, if they be right," which seems to mean, "If thy lips utter what is right, they will gather wisdom from my words and impart it to others."
23:12-16 Here is a parent instructing his child to give his mind to the Scriptures. Here is a parent correcting his child: accompanied with prayer, and blessed of God, it may prove a means of preventing his destruction. Here is a parent encouraging his child, telling him what would be for his good. And what a comfort it would be, if herein he answered his expectation! 17,18. The believer's expectation shall not be disappointed; the end of his trials, and of the sinner's prosperity, is at hand.
Yea, my reins shall rejoice,.... Which is only another phrase expressive of the same thing, and confirming the greatness of joy on the above occasion; not only his heart rejoiced, which was affectionately concerned for his son, near which he lay, the desires of which were frequently drawn out for his good, but his reins also; the seat of the afflictions rejoiced at it; showing how vehement, sincere, and hearty the joy was;
when thy lips speak right things; as they will, when the heart is wise; things agreeably to right reason, to the Scriptures of truth, the oracles of God; to the law and to the testimony; to the Gospel of Christ, and the doctrines of it; and such things as are savoury, pleasant, and profitable, and minister grace to the hearers. The Targum is,
