(20) Quicken me.--According to the written text, quicken us, an indication that the psalm is a hymn for congregational use. As for the change from singular to plural, that is common enough.

Depths . . .--Abysses, properly of water. (See Psalm 33:7.) Perhaps here with thought of the waters on which the earth was supposed to rest. If so, the image is the common one of a "sea of trouble."

Verse 20. - Thou, which hast showed me great and sore troubles, shalt quicken me again; or, according to another reading, which hast showed us - shalt deliver us. The change of number may be ascribed to the desire of the psalmist to unite his people with himself in the hopes of deliverance which he is expressing. And shalt bring me up again (rather, shalt bring us up again) from the depths of the earth. 'The "depths of the earth" is a metaphor for the extreme of misery and depression (comp. Psalm 88:6; Psalm 130:1).

71:14-24 The psalmist declares that the righteousness of Christ, and the great salvation obtained thereby, shall be the chosen subject of his discourse. Not on a sabbath only, but on every day of the week, of the year, of his life. Not merely at stated returns of solemn devotion, but on every occasion, all the day long. Why will he always dwell on this? Because he knew not the numbers thereof. It is impossible to measure the value or the fulness of these blessings. The righteousness is unspeakable, the salvation everlasting. God will not cast off his grey-headed servants when no longer capable of labouring as they have done. The Lord often strengthens his people in their souls, when nature is sinking into decay. And it is a debt which the old disciples of Christ owe to succeeding generations, to leave behind them a solemn testimony to the advantage of religion, and the truth of God's promises; and especially to the everlasting righteousness of the Redeemer. Assured of deliverance and victory, let us spend our days, while waiting the approach of death, in praising the Holy One of Israel with all our powers. And while speaking of his righteousness, and singing his praises, we shall rise above fears and infirmities, and have earnests of the joys of heaven. The work of redemption ought, above all God's works, to be spoken of by us in our praises. The Lamb that was slain, and has redeemed us to God, is worthy of all blessing and praise.Thou, which hast showed me great and sore troubles,.... Or, "made him to see" (g); that is, to experience. David had his troubles, and these were great, both as to quantity and quality; and very grievous and hard to be borne, and were very trying and afflictive: some outward, such as he endured when persecuted by Saul; and afterwards in his own family, though the incest of Ammon, the murder of him by Absalom, and Absalom's rebellion against him; the curses of Shimei, and the bickerings of the sons of Zeruiah; with many others: and some inward, arising from the corruptions of his heart, the hidings of God's face, and the temptations of Satan. His experience of all which he ascribes, not to instruments or second causes, but to God himself; who had either laid them upon him, or suffered them to befall him, for wise ends of his glory, and his servant's good. There is in this clause and the following, a "Keri" and a "Cetib"; according to the "Cetib", or writing in the text, it is, "who hast showed us"; and so the Targum renders it: but according to the "Keri" in the margin, and the points, it is as we read; so it is in the Septuagint and Oriental versions, and both may be retained; for David's troubles, and those of other saints, are much the same;

shalt quicken me again; either raise him from so great a death of afflictions, in which he seemed to be as a dead man, both by himself and others, to a more comfortable and happy state and condition, in which he might live more free from vexation and trouble: or, in a spiritual sense, quicken him, being dead and lifeless, in the exercise of grace, and discharge of duty; which is usually done by the word and ordinances, and to purpose, by the discoveries of the love of God, which excite grace, and animate to duty. And this is God's work, and may be called a quickening again in distinction from the first quickening, when dead in trespasses and sins;

and shalt bring me up again from the depths of the earth; expressive of a very low estate, either of body or mind, into which he had been brought; see Psalm 130:1. Could the psalm be understood of Christ, this and the preceding clause might be applied to his resurrection from the dead; see Ephesians 4:9; and to the resurrection of the saints; on which the faith of Christ and his people is exercised,
