Teach me to do thy will ... - To do that which will be agreeable or pleasing to thee; which will meet with thy approbation. That is, Teach me in the present emergency to do that which thou wilt approve; which will be wise; which will be best adapted to secure my deliverance and my safety.

Thy spirit is good - The spirit which guides those who trust in thee; the spirit with which "thou" dost guide people. That spirit is wise, prudent, judicious, reliable. It will not lead astray. Grant me "that" spirit, and I shall be certain that I am going in the right path. There is no certain evidence that the psalmist here refers distinctively to the Holy Spirit, considered as the Third Person of the Trinity; but the prayer is one for guidance from on high in the day of darkness and trouble. It is an acknowledgment of dependence on God for direction, and the expression of confidence that under the divine guidance he would not go astray.

Lead me into the land of uprightness - Or rather here, "land of evenness;" level ground; ground where I may walk without the dangers to which I am exposed where I am now, in a place of ambuscades, caverns, rocks, where I may be assailed at any moment without the power of seeing my enemy, or of defending myself. See this use of the word in the following places where it is rendered "plain," meaning a level country, Deuteronomy 3:10; Deuteronomy 4:43; Joshua 13:9, Joshua 13:16-17, Joshua 13:21; 1 Kings 20:23, 1 Kings 20:25; Psalm 27:11; Jeremiah 21:13; Jeremiah 48:8, Jeremiah 48:21; Zechariah 4:7. He desired to be led, as it were, into a "level" country where he might be safe. It is not a prayer, as would seem from our translation, to be so guided that he might lead an upright life. Such a prayer is proper, but it is not the prayer offered here.

Teach me to do thy will - רצונך retsonecha, thy pleasure. To be found doing the will of God is the only safe state for man.

Thy Spirit is good - The Author of every good desire and holy purpose.

Lead me - Let it lead me by its continued inspirations and counsels.

Into the land of uprightness - "Into a right land," Chaldee. Into the place where I shall be safe. The old Psalter has, Thi goste gude sal lede me into rygt lande.

Teach me to do thy will,.... Revealed in the word; which saints desire a greater knowledge of in order to do it, and in which they delight; and also are desirous of being taught, and to practise submission to the will of God under afflictions; which was now the case of the psalmist;

for thou art my God; his covenant God; and from whom all his afflictions came in a covenant way, and therefore desires to be instructed by him in them; see Jeremiah 31:18;

thy Spirit is good; thy holy good Spirit, as the Targum; the Spirit of thy holiness, as the Arabic version: the Holy Spirit of God is meant, the third Person in the Trinity; who is "good" essentially, being of the same nature and essence with the Father and Son, with God, who is only good; and effectively is the author of the good work of grace upon the heart, and of the several particular graces there implanted, and who performs many good offices to the saints;

lead me into the land of uprightness; or, "let thy good Spirit lead me into the land of uprightness" (z): either into a right land, as the Targum, where honesty prevails, and honest and upright men live; or, "through a plain way" (a), easy to be found, in which he should not err, and where would be no occasion of stumbling; or, "through the way of life", as the Syriac version; the way to eternal life, to heaven and happiness; the land where only truly righteous and upright persons dwell: such will be the new heavens and the new earth, as well as the ultimate state of glory, 2 Peter 3:13; and to this the Spirit of God is the leader and guide of his people, Psalm 48:14.

(z) So the Tigurine version, Musculus, Junius & Tremellius, Piscator, Cocceius. (a) "per terram planam", Tigurine version, Junius & Tremellius, Piscator.

{k} Teach me to {l} do thy will; for thou art my God: thy spirit is good; lead me into the land of uprightness.

(k) He confesses that both the knowledge and obedience of God's will comes by the Spirit of God, who teaches us by his word, gives understanding by his Spirit, and frames our hearts by his grace to obey him.

(l) That is, justly and aright, for as soon as we decline from God's will, we fall into error.

10. (Compare Ps 5:8; 27:11).

land of uprightness-literally, "an even land" (Ps 26:12).

143:7-12 David prays that God would be well pleased with him, and let him know that he was so. He pleads the wretchedness of his case, if God withdrew from him. But the night of distress and discouragement shall end in a morning of consolation and praise. He prays that he might be enlightened with the knowledge of God's will; and this is the first work of the Spirit. A good man does not ask the way in which is the most pleasant walking, but what is the right way. Not only show me what thy will is, but teach me how to do it. Those who have the Lord for their God, have his Spirit for their Guide; they are led by the Spirit. He prays that he might be enlivened to do God's will. But we should especially seek the destruction of our sins, our worst enemies, that we may be devotedly God's servants.
