This and the next verse are the words, either,
1. Of God; whom David brings in as returning this answer to his prayers, and the profession of his trust in God. Or rather,
2. Of David himself; who having received singular favours from God, and having declared what the godly would do upon that occasion, Psalms 32:6, he now undertakes to instruct the wicked what they should do; which he doth, partly to express his thankfulness to God for delivering himself, and his, zeal to advance the honour and service of God in the world; partly, as an act of justice, that he might make some amends to those whom he had injured, and provoke them to repentance, whom by his sins he had scandalized, and either drawn to sin, or encouraged and hardened in sin, which he was obliged and did promise to do upon this or the like occasion, Psalms 51:13; and partly, for the discharge of his office and duty, as he was both a king and a prophet, and a good man; in all which capacities he was obliged to endeavour the conversion and salvation of sinners. Thee; thee, O sinner, whosoever thou art, who hast no understanding, but art a wicked man, as the two following verses explain it. He speaks this to the generality of impenitent sinners, as the next verse shows, which begins in the plural number, Be not ye, &c.; only he expresseth it here singularly, as appealing and applying himself particularly to the conscience of every individual person, which he thought the most effectual way of proceeding, as he had found in himself, when Nathan applied his indefinite discourse to him, saying, Thou art the man. In the way which thou shalt go, i.e. in which thou oughtest to walk; the future tense oft noting a man's duty, as Genesis 20:9 Zechariah 1:6. I will guide thee with mine eye; I will lend thee the eyes of my mind. Or, I will be to thee instead of eyes, as the phrase is, Numbers 10:31, to advise, and direct, and caution thee; which I am able to do, not only by those gifts and graces which God hath given me, but also from my own experience. I will guide thee as the rider doth his horse, to which the person to be guided is compared, Psalms 32:9; or as a master doth his scholar; or as a guide doth him who knoweth not the right way. Or the words may be thus rendered, I will give thee counsel, mine eye shall be upon thee, as it is more fully expressed, Genesis 44:21 Jeremiah 24:6, Jeremiah 40:4, i.e. I will watch over thee, and instruct or admonish thee, as I have occasion.
