Carl Friedrich Keil and Franz Delitzsch Old Testament Commentary
14 From the fruit which the mouth of the man bringeth forth is he satisfied with good,
And what the hands of the man accomplish returns back to him.
The proverb finds its final verification in the last judgment (cf. Mat 12:37), but it is also illustrated in the present life. If the mouth of a man bringeth forth fruit - namely, the fruit of wholesome doctrine, of right guidance, of comforting exhortation, of peace-bringing consolation for others - this fruit is also to his own advantage, he richly enjoys the good which flows out of his own mouth, the blessing he bestows is also a blessing for himself. The same also is the case with the actions of a man. That which is done, or the service which is rendered by his hands, comes back to him as a reward or as a punishment. גּמוּל signifies primarily accomplishment, execution, and is a twofold, double-sided conception: a rendering of good or evil, and merit on the side of men (whether merited reward or merited punishment), as well as recompense, requital on the side of God. The first line is repeated, somewhat altered, at Pro 13:2; Pro 18:20. The whole proverb is prophetically echoed in Isa 3:10. The Kerı̂ ישׁיב has Jahve as the subject, or rather the subject remains undefined, and "one requites him" is equivalent to: it is requited to him. The Chethı̂b seems to us more expressive; but this use of the active with the undefined subject, instead of the passive, is certainly as much in the Mishle style (cf. Pro 13:21) as the development of the subject of the clause from a foregoing genitive.
John Gill Bible Commentary
A man shall be satisfied with good by the fruit of his mouth,.... The wholesome advice, the good instruction, and sound doctrine he delivers to others, which are the fruit of his lips, and come forth by them from his heart; these redound to his own advantage, are not only a satisfaction to his mind upon reflection, but because of these he is filled with good things, even to satiety, both in this life and that to come; see Ti1 4:6; or a "man shall be satisfied with good from the fruit of the mouth"; or "be satisfied from the fruit of the mouth of a man" (z); that is, of another man; either of a private man, by his prayers, by the account he gives of his own experience, by the conversation he has with him about the truths of the Gospel; or of a faithful minister of the word, who is the means of feeding the souls of men with good things, even to satisfaction, with the wholesome words of our Lord Jesus Christ, with the sincere milk of the word, with the bread of life, even with the finest of the wheat;
and the recompence of a man's hand shall be rendered unto him; if his words turn to his account, much more his works; if he is filled with good things for the sake of the one, much more will he be recompensed in a way of grace on account of the other; and not for the one without the other, nor for words without works: or "the recompence of a man's hands", or of his works which his hands do, "he shall render to him" (a); that is, God, who renders to every man according to his works; which serves not to establish the doctrine of merit, but to show the goodness and grace of God in taking notice of and accepting the imperfect works of men through Christ, and for his sake.

Matthew Henry Bible Commentary
We are here assured, for our quickening to every good word and work, 1. That even good words will turn to a good account (Pro 12:14): A man shall be satisfied with good (that is, he shall gain present comfort, that inward pleasure which is truly satisfying) by the fruit of his mouth, by the good he does with his pious discourse and prudent advice. While we are teaching others we may ourselves learn, and feed on the bread of life we break to others. 2. That good works, much more, will be abundantly rewarded: The recompence of a man's hands for all his work and labour of love, all he has done for the glory of God and the good of his generation, shall be rendered unto him, and he shall reap as he has sown. Or it may be understood of the general rule of justice; God will render to every man according to his work, Rom 2:6.
