Proverbs 9:9
Give instruction to a wise man, and he will be yet wiser: teach a just man, and he will increase in learning.
Give instruction to a wise man,.... In the Hebrew text it is only "give to a wise man"; give him reproof, correction, chastisement, doctrine, or instruction, be it what it will, he will be the better for it. The Septuagint, Vulgate Latin, Syriac, and Arabic versions, render it, "give occasion"; to him of showing his wisdom and of improving in it:
and he will be yet wiser; he will learn something by every him that is given him, whether it be by way of rebuke, or by way of instruction;
teach a just man; one that is truly so, that has seen the insufficiency of his own righteousness, and has renounced that, and does not trust in it; and who has learned Christ, as the Lord his righteousness; has seen the glory, fulness, and suitableness of his righteousness, and trusts unto it and depends upon it; and in consequence of this lives soberly, righteously, and godly; teach such a man the doctrines of the Gospel, and every lesson of obedience and duty,
and he will increase in learning; he will grow in grace, and in the knowledge of Christ and all divine things; see Matthew 13:12.
