Who is the man. By again recalling to his mind the character in which God manifests himself towards his servants, he derives new strength and courage. For we have said, that nothing more readily occurs than a relaxation in earnest and attentive prayer, unless it be sustained by the recollection of God's promises. There can, however, be no doubt, that David both accuses himself, and by entertaining a better hope, takes encouragement to continue in the fear of God. In the first place, by intimating that men are destitute of right understanding and sound judgment, because they yield not themselves to be governed by God with reverence and fear, he imputes it to his own indolence, that by reason of the darkness of his mind, he had wandered so far astray after his own lusts; and yet, on the other hand, he promises himself the guidance and direction of the Holy Spirit, if he only yield himself wholly to God, and show that he is willing to learn. Moreover, the interrogatory style of speaking, which he here employs, seems designed to show how few there are who fear God: for, although all men in general pray, and manifest some appearance of piety, yet where is there one among so many who is really in earnest? Instead of this, almost all men indulge themselves in their own drowsiness. The fear of God, therefore, is very rare; and on this account it is that the world, for the most part, continues destitute of the Spirit of counsel and wisdom. Some interpreters render the word choose in the present tense, instead of the future, shall choose; as if it had been said, that God shows the way which he approves, and in which he wishes men to walk. With this interpretation I cannot agree; for, in my judgment, the word choose rather refers to every individual; as if it had been said, Provided we are disposed to fear God, he will not be wanting on his part, but will always direct us by the Spirit of wisdom to choose the right way. When we are called upon to adopt some particular course in life, we find ourselves as it were placed between two ways, and know not which of them to follow; nay, in almost all our affairs we are held in suspense and doubt, unless God appear to show us the way. David therefore says, that although men know not what is right, and what they ought to choose, yet provided they submit to God with pious docility of mind, and are willing to follow him, he will always manifest himself towards them as a sure and faithful guide. As, however, the fear of God is not naturally in us, it were foolish for any man to argue from this place, that God does not begin to take care of men until, by their own previous efforts, they insinuate themselves into his favor, that he may aid them in their pious endeavors. David has just declared, that this grace comes directly from God, when he says that God teaches the transgressors: and now he adds, in the second place, that after men have once been subdued and moulded to meekness of spirit, God still takes them under his charge, guiding and directing them till they are able, by the illumination of the Holy Spirit, to know what is their duty.

What man is he - Who is he. The statement in this verse is intended to include every man; or to be universal. Wherever one is found who has the character here referred to, or whoever he may be, of him what is here affirmed will be true, that God will lead him in the way that he shall choose.
That feareth the Lord - That is, a true worshipper of Yahweh, or that is truly a pious man: Psalm 5:7. "Him shall he teach." He will guide, or instruct him. See Psalm 25:9.
In the way that he shall choose - The way that the person ought to choose; or, in other words, in the right way. It is not the way that God shall choose, but the way that the pious person ought to choose: God will so instruct him that he shall find the true path.

That feareth the Lord - Who has a proper apprehension of his holiness, justice, and truth; and who, at the same time, sees himself a fallen spirit, and a transgressor of God's holy law, and consequently under the curse. That is the person that truly and reverently fears God.
Him shall he teach - Such a person has a teachable spirit.
The way that he shall choose - The way that in the course of Providence he has chosen, as the way in which he is to gain things honest in the sight of all men; God will bless him in it, and give him as much earthly prosperity as may be useful to his soul in his secular vocation.

What (i) man [is] he that feareth the LORD? him shall he teach in the way [that] he shall (k) choose.
(i) Meaning, the number is very small.
(k) He will direct such with his spirit to follow the right way.

What man is he that feareth the Lord? That is, how happy a man is he! and one that fears the Lord is one that has the fear of God put into his heart, as a blessing of the covenant of grace before spoken of; who fears the Lord, not on account of the punishment of sin, but under the influence of the pardon of it, and for his goodness's sake; who loves the Lord, trusts in him, is careful not to offend him, hates sin, and avoids it, and has a strict regard to the worship of God in all its parts and branches, and performs it in fear; or who serves the Lord with reverence and godly fear. The description of this man's happiness follows in this verse and Psalm 25:12,
him shall he teach in the way that he shall choose; either which the man that fears God shall choose, which is the way of truth and duty, Psalm 119:30; or the way which God prescribes to him, and is well pleasing in his sight, who teaches to profit, and leads in the way his people should go; and a great happiness it is for a man to have his steps ordered by the Lord and his goings directed by him.

What he asks for himself is the common lot of all the pious.

The question: quisnam est vir, which resembles Psalm 34:13; Psalm 107:43; Isaiah 50:10, is only propounded in order to draw attention to the person who bears the character described, and then to state what such an one has to expect. In prose we should have a relative antecedent clause instead, viz., qui (quisquis) talis est qui Dominum vereatur.
(Note: The verb ver-eri, which signifies "to guard one's self, defend one's self from anything" according to its radical notion, has nothing to do with ירא (ורא).)
The attributive יבהר, (viam) quam eligat (cf. Isaiah 48:17), might also be referred to God: in which He takes delight (lxx); but parallels like Psalm 119:30, Psalm 119:173, favour the rendering: which he should choose. Among all the blessings which fall to the lot of him who fears God, the first place is given to this, that God raises him above the vacillation and hesitancy of human opinion.
