For thy name's sake, O Jehovah! etc. By this expression he makes it still more clear that it was entirely of God's free mercy that he looked for deliverance; for, had he brought forward anything of his own, the cause would not have been in God, and only in God. He is said to help us for his own name's sake, when, although he discovers nothing in us to conciliate his favor, he is induced to interpose of his mere goodness. To the same effect is the term righteousness; for God, as I have said elsewhere, has made the deliverance of his people a means of illustrating his righteousness. He at the same time repeats what he had said as to the extraordinary extent of his afflictions: in seeking to be quickened or made alive, he declares himself to be exanimated, and that he must remain under the power of death, if the God who has the issues of life did not recover him by a species of resurrection.

Quicken me, O Lord - Give me life. Compare the notes at Ephesians 2:1. Make me equal to my circumstances, for I am ready to sink and to yield.
For thy name's sake - For thine honor. Compare the notes at Daniel 9:17-18. It is in thy cause. Thou wilt thus show thy power, thy faithfulness, thy goodness. Thou wilt thus get honor to thyself. This is the highest motive which can influence us - that God may be glorified.
For thy righteousness' sake - Thy justice; thy truth; thy faithfulness in performing thy promises and pledges.
Bring my soul out of trouble - Out of this trouble and distress. See the notes at Psalm 25:17.

Quicken me - I am as a dead man, and my hopes are almost dead within me.

Quicken me, O Lord, for thy name's sake,.... Being like one dead, Psalm 143:3; that is, revive and cheer his drooping spirit, ready to fail, being overwhelmed within him, Psalm 143:4; as well as revive the work of grace in him; and quicken his soul to the exercise of grace, and discharge of duty; and this he desires not only for his own soul's good, but for the glory of God, that his name might be hououred, and not blasphemed;
for thy righteousness' sake bring my soul out of trouble; for as he had his bodily troubles and other outward affliction, he had soul troubles, through the corruptions of his nature, the temptations of Satan, and the hidings of God's face; which beset him around, and greatly straitened and afflicted him, and filled him with doubts and fears; from all which he desires deliverance, for the sake of the righteousness of God, or his faithfulness to his promise, that he would deliver his people in distress when they called upon him; See Gill on Psalm 143:1. This interprets the meaning of the petition in Psalm 142:7.

(Compare Psalm 23:3; Psalm 119:156).
