After David has disburdened his griefs and troubles into the bosom of God, he now, as it were, assumes a new character. And, without doubt, he had been afflicted with long-continued despondency of spirit before he could recover himself, and attain to such a degree of assurance as he here displays; for we have already seen that he had spent many nights in continual weeping. Now, the more he had been distressed and wearied by the long delay of his deliverance, with so much the more alacrity does he stir up himself to sing of victory. Directing his discourse against his adversaries, he represents it as not the least part of his temptations that ungodly men triumphed over him, and derided him as lost, and in a hopeless condition; for we know with what insolence their pride and cruelty magnify themselves against the children of God, when they see them oppressed under the cross. And to this Satan moves them, in order to drive the faithful to despair, when they see their hope made the subject of mockery. This passage teaches us, that the grace of God is the only light of life to the godly; and that, as soon as He has manifested some token of his anger, they are not only greatly afraid, but also, as it were, plunged into the darkness of death; while, on the other hand, as soon as they discover anew that God is merciful to them, they are immediately restored to life. David, it is to be noticed, repeats three times that his prayers were heard, by which he testifies that he ascribes his deliverance to God, and confirms himself in this confidence, that he had not betaken himself to God in vain. And if we would receive any fruit from our prayers, we must believe that God's ears have not been shut against them. By the word weeping, [1] he not only indicates vehemence and earnestness, but also intimates that he had been wholly occupied in mourning and sorrowful lamentations. The confidence and security which David takes to himself from the favor of God ought also to be noticed. From this, we are taught that there is nothing in the whole world, whatever it may be, and whatever opposition it may make to us, which we may not despise, if we are fully persuaded of our being beloved by God; and by this also we understand what his fatherly love can do for us. By the adverb suddenly, he signifies, that when there is apparently no means of delivering the faithful from affliction, and when all seems desperate or hopeless, then they are delivered by the power of God contrary to all expectation. When God suddenly changes men's afflicted condition into one of joy and happiness, he thereby manifests more illustriously his power, and makes it appear the more wonderful.

Footnotes

1 - "The voice of my weeping, my loud weeping." says Hengstenberg, and then he adds, quoting from Roberts' Orient. Illustr. of the Sacred Scrip., "Silent grief is not much known in the East. Hence, when the people speak of lamentation, they say, Have I not heard the voice of his mourning?"

Depart from me, all ye workers of iniquity - Referring, by the "workers of iniquity," to his enemies, as if they now surrounded him, and calling on them "now" to leave him, since God had heard his prayer, and they could not be successful in their purposes. This is an indirect but most emphatic way of saying that God had heard his prayer; and the sentiment in this verse is strongly in contrast with the desponding state of feeling - the deep and dreadful sorrow - indicated in the previous verses. Light broke in suddenly upon him; his prayer had come up before God, and, in some way, he was assured that it would be answered. Already he sees his enemies scattered, and his own cause triumphant; and in this exulting feeling he addresses his foes, and commands them to leave him. This is, therefore, a remarkable and striking proof that prayer may be heard, even while we are speaking to God (compare Isaiah 65:24); that the assurance may be conveyed suddenly to the mind that God will hear and answer the prayer which is addressed to him; and also a beautiful illustration of the effect of this on a mind overwhelmed with trouble and sorrow, in giving it calmness and peace.
For the Lord hath heard - That is, my prayer has ascended before him, and I am certain that he regards it favorably, and will answer it. "In what way" he had this assurance he does not inform us. As he was an inspired man, we may suppose that the assurance was given to him directly by the Holy Spirit. "We" are not to expect the "same kind" of assurance that our prayers are heard; we are to look for no revelation to that effect; but there may be "as real" an intimation to the mind that our prayers are heard - as real "evidence" - as in this case. There may be a firm confidence of the mind that God is a hearer of prayer now coming to the soul with the freshness of a new conviction of that truth; and there may be, in trouble and sorrow, a sweet calmness and peace breathed through the soul - an assurance that all will be right and well, as if the prayer were heard, and such as there would be if we were assured by direct revelation that it is heard. The Spirit of God can produce this in our case as really as he did in the case of David.
The voice of my weeping - The voice of prayer that accompanied my weeping, or the voice of the weeping itself - the cry of anguish and distress which was in itself of the nature of prayer.

Depart from me, all ye workers of iniquity - It seems that while he was suffering grievously through the disease, his enemies had insulted and mocked him; - upbraided him with his transgressions, not to increase his penitence, but to cast him into despair.
The Lord hath heard the voice of my weeping - The Lord pitifully beheld the sorrows of his heart, and mercifully forgave his sins.

(e) Depart from me, all ye workers of iniquity; for the LORD hath heard the voice of my weeping.
(e) God sends comfort and boldness in affliction, that we may triumph over our enemies.

Depart from me, all ye workers of iniquity,.... The psalmist being fully assured that God had heard his prayer, that he should recover from his disorder, or be delivered out of his calamities, whether corporeal or spiritual, has on a sudden a spring of joy, faith, and comfort; as sometimes there is a quick transition from comfortable to uncomfortable frames; see Psalm 30:7; so on the contrary, there is as quick a passage from uncomfortable to comfortable ones; see Lamentations 3:18; who may be called "workers of iniquity" See Gill on Psalm 5:5; and these were either his open enemies, as Saul and his men, or Absalom and the conspirators with him, whom he bids to cease from following and pursuing after him; or his secret ones, hypocritical courtiers, that were about him, who were wishing and hoping for his death. It is the lot of God's people to be among the workers of iniquity; Lot was among the Sodomites, David was in Meshech and in the tents of Kedar, Isaiah was among men of unclean lips; Christ's lily is among thorns, and his sheep among goats; and though in some respects a civil conversation with wicked men cannot be avoided, for then good men must needs go out of the world; yet as little company should be kept with them as can be, and no fellowship should be had with them in sinful practices, nor in superstitious worship; and though there will not be a full and final separation from them in the present state of things, there will be hereafter, when these very words will be used by David's antitype, the Lord Jesus Christ; not only to profane sinners, but to carnal professors of religion, who have herded themselves with the people of God, Matthew 25:41. The reason why the psalmist took heart and courage, and ordered his wicked persecutors, or sycophants, to be gone from him, was his assurance of being heard by the Lord;
for the Lord hath heard the voice of my weeping; referring to what is said Psalm 6:6; he had not only lifted up his voice in prayer, but he had wept and made supplication, as Jacob did, Hosea 12:4; sometimes God brings his people to the throne of grace weeping, and with supplications leads them, Jeremiah 31:9; and then hears their cry and answers them.

What a sudden change is here! Having made his request known to God, the psalmist is confident that his sorrow will be turned into joy. By the workings of God's grace upon his heart, he knew his prayer was accepted, and did not doubt but it would, in due time, be answered. His prayers will be accepted, coming up out of the hands of Christ the Mediator. The word signifies prayer made to God, the righteous Judge, as the God of his righteousness, who would plead his cause, and right his wrongs. A believer, through the blood and righteousness of Christ, can go to God as a righteous God, and plead with him for pardon and cleansing, who is just and faithful to grant both. He prays for the conversion of his enemies, or foretells their ruin.

Assured of God's hearing, he suddenly defies his enemies by an address indicating that he no longer fears them.

(Hebrews.: 6:9-11) Even before his plaintive prayer is ended the divine light and comfort come quickly into his heart, as Frisch says in his "Neuklingende Harfe Davids." His enemies mock him as one forsaken of God, but even in the face of his enemies he becomes conscious that this is not his condition. Thrice in Psalm 6:9, Psalm 6:10 his confidence that God will answer him flashes forth: He hears his loud sobbing, the voice of his weeping that rises towards heaven, He hears his supplication, and He graciously accepts his prayer. The twofold שׁמע expresses the fact and יקח its consequence. That which he seems to have to suffer, shall in reality be the lot of his enemies, viz., the end of those who are rejected of God: they shall be put to shame. The בּושׁ, Syr. behet, Chald. בּהת, בּהת, which we meet with here for the first time, is not connected with the Arab. bht, but (since the Old Arabic as a rule has t` as a mediating vowel between ש and t, )ת with Arab. bât, which signifies "to turn up and scatter about things that lie together (either beside or upon each other)" eruere et diruere, disturbare, - a root which also appears in the reduplicated form Arab. bṯṯ: to root up and disperse, whence Arab. battun, sorrow and anxiety, according to which therefore בּושׁ (= בּושׁ as Arab. bâta = bawata) prop. signifies disturbare, to be perplexed, lose one's self-control, and denotes shame according to a similar, but somewhat differently applied conception to confundi, συγχεῖσθαι, συγχύνεσθαι. ויבּהלוּ points back to Psalm 6:2, Psalm 6:3 : the lot at which the malicious have rejoiced, shall come upon themselves. As is implied in יבשׁוּ ישׁבוּ, a higher power turns back the assailants filled with shame (Psalm 9:4; Psalm 35:4).
What an impressive finish we have here in these three Milels, jashûbu jebôshu rāga), in relation to the tripping measure of the preceding words addressed to his enemies! And, if not intentional, yet how remarkable is the coincidence, that shame follows the involuntary reverse of the foes, and that יבשׁו in its letters and sound is the reverse of ישׁבו! What music there is in the Psalter! If composers could but understand it!!

Hath heard - By the workings of God's grace upon his heart, he knew his prayer was accepted. His tears had a voice, in the ears of the God of mercy. Silent tears are no speechless ones. Our tears are cries to God.
