Verse 88. - Quicken me after thy loving-kindness (comp. vers. 25, 37, 44, 107, 149, 156, 159). So shall I keep the testimony of thy mouth (compare "the law of thy mouth," in ver. 72). It is God's "quickening" - i.e. his life-giving grace - which alone enables his servants to observe and keep his commandments.

119:81-88 The psalmist sought deliverance from his sins, his foes, and his fears. Hope deferred made him faint; his eyes failed by looking out for this expected salvation. But when the eyes fail, yet faith must not. His affliction was great. He was become like a leathern bottle, which, if hung up in the smoke, is dried and shrivelled up. We must ever be mindful of God's statutes. The days of the believer's mourning shall be ended; they are but for a moment, compared with eternal happiness. His enemies used craft as well as power for his ruin, in contempt of the law of God. The commandments of God are true and faithful guides in the path of peace and safety. We may best expect help from God when, like our Master, we do well and suffer for it. Wicked men may almost consume the believer upon earth, but he would sooner forsake all than forsake the word of the Lord. We should depend upon the grace of God for strength to do every good work. The surest token of God's good-will toward us, is his good work in us.Quicken me after thy lovingkindness,.... According to it, and with it; let me have some discoveries of it, and of interest in it; and that will quicken me, revive and comfort me, under all the reproaches, ill usage, and persecutions of men. The love of God shed abroad in the heart comforts and supports under all sorts of afflictions; it quickens the graces of the Spirit, and brings them forth into lively exercise, as faith, hope, and love; and to a diligent and fervent discharge of every duty: it constrains to love the Lord, and live to him, to his glory, in obedience to his will;

so shall I keep the testimony of thy mouth; the word of God, which comes out of his mouth, testifies of him, and of his mind and will; and which is to be received and observed, as being greater than the testimony of men, 1 John 5:9.
