VAU. Let thy mercy also come upon me, O Lord: thy salvation according to thy word.

“"And let Thy loving mercy come also unto us, O Lord" (ver. 41). This sentence seems annexed to the foregoing: for he doth not say, Let it come unto me, but, "And let it come unto me."...What then doth he here pray for, save that through His loving mercy who commanded, he may perform the commandments which he hath coveted? For he explaineth in some degree what he meant by adding, "even Thy salvation, according to Thy word:" that is, according to Thy promise. Whence the Apostle desireth us to be understood as the children of promise: that we may not imagine that what we are is our own work, but refer the whole to the grace of God....Christ Himself is the Salvation of God, so that the whole body of Christ may say, "By the grace of God I am what I am."”

“And take not the word of truth utterly out of my mouth,.... The Scriptures, which are by divine inspiration, come from the God of truth, contain nothing but truth in them, and are called "the Scriptures of truth", Dan 10:21. Or the Gospel, which is often so called, Eph 1:13; This comes from God, who cannot lie, and is a declaration of his mind and will concerning the salvation of men; in which Christ, who is the truth, is concerned, being the author, preacher, and substance of it; into which the Spirit of truth leads men, and makes it useful and effectual; which has many eminent and important truths in it, and nothing but truth, and stands opposed to the law, which is typical and shadowy, and to everything that is a falsehood and a lie. This the psalmist desires might not be taken out of his mouth, but kept in it as a sweet morsel there, rolled under his tongue; be eaten and fed upon by him, and be the rejoicing of his heart. Or his sense is, that he might not be left under a temptation to conceal, drop, or deny the word of truth, or be ashamed to own and confess it before men; but at all times, and upon all occasions, publicly declare it, and his faith in it: at least he desires that it might not "utterly" cease from him, or be wholly neglected by him, and he entirely apostatize. Some join the word rendered "utterly", and which signifies "exceedingly", with "the word of truth", thus: "take not out of my mouth the word of truth, which is exceedingly so"; that is, exceedingly true, to the highest degree (e); for I have hoped in thy judgments; or, "have waited for thy judgments" (f): either the judgments of God upon sinners, especially on apostates, which he knew would be very sore and severe, their last estate being worse than the first; or rather the last judgment, when those that confess Christ and his truths shall be confessed by him; and those that deny him and his Gospel will be denied by him: though it may be best of all to understand it of the word of God, and the doctrines of it, which the psalmist had an exceeding great regard unto, hoped, waited, and even longed for; see Psa 119:20. (e) So Gussetius Ebr. Comment. p. 452. "verbum veritatis usque valde", Pagninus, Montanus; so Musculus, Junius & Tremellius. (f) "ad judicia tua expectavi", Pagninus, Montanus; "judicia tua expecto", Tigurine version, Musculus, Vatablus, Gejerus; so Junius & Tremellius, Piscator.”

“The eightfold Vav. He prays for the grace of true and fearlessly joyous confession. The lxx renders Psa 119:41: καὶ ἔλθοι ἐπ ̓ ἐμε ̓ τὸ ἔλεός σου; but the Targum and Jerome rightly (cf. Psa 119:77, Isa 63:7) have the plural: God's proofs of loving-kindness in accordance with His promises will put him in the position that he will not be obliged to be dumb in the presence of him who reproaches him (חרף, prop. a plucker, cf. Arab. charûf, a lamb = a plucker of leaves or grass), but will be able to answer him on the ground of his own experience. The verb ענה, which in itself has many meanings, acquires the signification "to give an answer" through the word, דּבר, that is added (synon. השׁיב דּבר). Psa 119:43 also refers to the duty of confessing God. The meaning of the prayer is, that God may not suffer him to come to such a pass that he will be utterly unable to witness for the truth; for language dies away in the mouth of him who is unworthy of its before God. The writer has no fear of this for himself, for his hope is set towards God's judgments (למשׁפּטך, defective plural, as also in Psa 119:149; in proof of which, compare Psa 119:156 and Psa 119:175), his confidence takes its stand upon them. The futures which follow from Psa 119:44 to Psa 119:48 declare that what he would willingly do by the grace of God, and strives to do, is to walk בּרחבה, in a broad space (elsewhere בּמּרחב), therefore unstraitened, which in this instance is not equivalent to happily, but courageously and unconstrainedly, without allowing myself to be intimidated, and said of inward freedom which makes itself known outwardly. In Psa 119:46 the Vulgate renders: Et loquebar de (in) testimoniis tuis in conspectu regum et non confundebar - the motto of the Augsburg Confession, to which it was adapted especially in connection with this historical interpretation of the two verbs, which does not correspond to the original text. The lifting up of the hands in Psa 119:48 is an expression of fervent longing desire, as in connection with prayer, Psa 28:2; Psa 63:5; Psa 134:2; Psa 141:2, and frequently. The second אשׁר אהבתי is open to the suspicion of being an inadvertent repetition. שׂיח בּ (synon. בּ הגה) signifies a still or audible meditating that is absorbed in the object.”
