He sent down from above. Here there is briefly shown the drift of the sublime and magnificent narrative which has now passed under our review, namely, to teach us that David at length emerged from the profound abyss of his troubles, neither by his own skill, nor by the aid of men, but that he was drawn out of them by the hand of God. When God defends and preserves us wonderfully and by extraordinary means, he is said in Scripture language to send down succor from above; and this sending is set in opposition to human and earthly aids, on which we usually place a mistaken and an undue confidence. I do not disapprove of the opinion of those who consider this as referring to the angels, but I understand it in a more general sense; for by whatever means we are preserved, it is God who having his creatures ready at his nod to do his will, appoints them to take charge of us, and girds or prepares them for succouring us. But, although every kind of aid comes from heaven, David, with good reason, affirms that God had stretched out his hand from on high to deliver him. In speaking thus, he meant to place the astonishing benefit referred to, by way of eminence, above others of a more common kind; and besides, there is in this expression a tacit comparison between the unusual exercise of the power of God here celebrated, and the common and ordinary means by which he succours his people. When he says, that God drew him out of great waters, it is a metaphorical form of expression. By comparing the cruelty of his enemies to impetuous torrents, by which he might have been swallowed up a hundred times, he expresses more clearly the greatness of the danger; as if he had said, I have, contrary to the expectation of men, escaped, and been delivered from a deep abyss in which I was ready to be overwhelmed. In the following verse he expresses the thing simply and without a figure, declaring that he had been delivered from a strong enemy, [1] who mortally hated and persecuted him. The more to exalt and magnify the power of God, he directs our attention to this circumstance, that no strength or power of men had been able to prevent God from saving him, even when he was reduced to the greatest extremity of distress. As in the end of the verse there is the Hebrew particle ky, ki, which generally denotes the cause of what is predicated, almost all interpreters agree in explaining the verse thus: God has succoured me from above, because my enemies were so numerous and so strong that no relief was to be expected by the mere aid of men. From this we deduce a very profitable doctrine, namely, that the most seasonable time for God to aid his people is when they are unable to sustain the assaults of their enemies, or rather, when, broken and afflicted, they sink under their violence, like the wretched man who having in a shipwreck lost all hope of being able to swim to the shore, sinks with great rapidity to the bottom of the deep. The particle yk, ki, however, might also be explained by the adversative particle although, in this way: Although the enemies of David were superior to him in number and power, he nevertheless was saved.

Footnotes

1 - Bishop Patrick paraphrases the verse thus:-- "He delivered me first from that mighty giant, Goliath, and then from Saul, whose power I was not able to withstand; and afterwards from the Philistines and Syrians, and many other nations, whose forces were far superior unto mine, and whose hatred instigated them to do all they could to destroy me."

He sent from above - He interposed to save me. All these manifestations of the divine interposition were from above, or from heaven; all came from God.
He took me - He took hold on me; he rescued me.
He drew me out of many waters - Margin, great waters. Waters are often expressive of calamity and trouble, Psalm 46:3; Psalm 69:1; Psalm 73:10; Psalm 124:4-5. The meaning here is, that God had rescued him out of the many troubles and dangers that encompassed him, as if he had fallen into the sea and was in danger of perishing.

He drew me out of many waters - Here the allusion is still carried on. The waters thus poured out were sweeping the people away; but God, by a miraculous interference, sent and drew David out. Sometimes waters are used to denote multitudes of people; and here the word may have that reference; multitudes were gathered together against David, but God delivered him from them all. This seems to be countenanced by the following verse.

He sent from above, he took me, he drew me out of many (m) waters.
(m) Out of many great dangers.

He sent from above,.... Either his hand, as in Psalm 144:7; he exerted and displayed his mighty power in raising Christ from the dead; or he sent help from his sanctuary; as in Psalm 20:2; and helped and strengthened him in a day of salvation; or when he wrought out the salvation of his people; or "he sent his word", as in Psalm 107:20; his word of command, to take up his life again, as he had given it to lay it down, John 10:18. The Targum is, he sent his prophets; but it may be much better supplied, he sent his angels, or an angel; as he did at his resurrection, who rolled away the stone from the sepulchre, as a token of his justification and discharge: so Jarchi interprets it, he sent his angels; and Aben Ezra supplies it thus,
"he sent his word or his angel:''
unless the sense should be, as Cocceius suggests, he sent a cloud from above, which was done at Christ's ascension, and which received him out of the sight of the apostles, Acts 1:9. Since it follows,
he took me; that is, up to heaven; thither Christ was carried in a cloud, one of God's chariots, he sent for him; and where he is received, and will be retained until his second coming; though rather the sense is, he took me by the hand:
he drew me out of many waters. This is said either in allusion to Moses, who had his name from his being drawn out of the water, Exodus 2:10; and who was an eminent type of Christ; and this is the only place where the Hebrew word is made use of from whence he had his name; or else to a man plunged in water ready to be drowned; see Psalm 69:1. By these "many waters" may be meant the many afflictions, sorrows, and sufferings from which Christ was freed, when raised from the dead, and highly exalted and crowned with glory and honour; and the torrent of sins which flowed in upon him at the time he was made sin for his people, from which he was justified when risen; and so will appear a second time without sin unto salvation; and the wrath of God, the waves and billows of which went over him, and compassed him about as water, at the time of his sufferings; from which he was delivered when he was shown the path of life, and entered into the presence of God, and sat at his right hand, where are joys and pleasures for evermore; and also his grand enemy Satan, with his principalities and powers, who came in like a flood upon him; but he destroyed him and spoiled them; and particularly the floods of ungodly men, spoken of in Psalm 18:4; seem to be here designed; compare with this Psalm 144:7; "so many waters" signify many people and nations, Revelation 17:15; and accordingly the Targum is,
"he delivered me from many people.''
This was true of Christ when risen and ascended; he was then separate from sinners, and made higher than the heavens; and this sense is confirmed by the following words, where what is expressed figuratively here is there literally explained.

from above--As seated on a throne, directing these terrible scenes, God--
sent--His hand (Psalm 144:7), reached down to His humble worshipper, and delivered him.
many waters--calamities (Job 30:14; Psalm 124:4-5).

(Hebrews.: 18:17-20) Then Jahve stretches out His hand from above into the deep chasm and draws up the sinking one. The verb שׁלח occurs also in prose (2-Samuel 6:6) without יד (Psalm 57:4, cf. on the other hand the borrowed passage, Psalm 144:7) in the signification to reach (after anything). The verb משׁה, however, is only found in one other instance, viz., Exodus 2:10, as the root (transferred from the Egyptian into the Hebrew) of the name of Moses, and even Luther saw in it an historical allusion, "He hath made a Moses of me," He hath drawn me out of great (many) waters, which had well nigh swallowed me up, as He did Moses out of the waters of the Nile, in which he would have perished. This figurative language is followed, in Psalm 18:18, by its interpretation, just as in Psalm 144:7 the "great waters" are explained by מיּד בּני נכר, which, however, is not suitable here, or at least is too limited.
With Psalm 18:17 the hymn has reached the climax of epic description, from which it now descends in a tone that becomes more and more lyrical. In the combination איבי עז, עז is not an adverbial accusative, but an adjective, like רוּחך טובה Psalm 143:10, and ὁ ἀνὴρ ἀγαθός (Hebrerbrief S. 353). כּי introduces the reason for the interposition of the divine omnipotence, viz., the superior strength of the foe and the weakness of the oppressed one. On the day of his איד, i.e., (vid., on Psalm 31:12) his load or calamity, when he was altogether a homeless and almost defenceless fugitive, they came upon him (קדּם Psalm 17:13), cutting off all possible means of delivering himself, but Jahve became the fugitive's staff (Psalm 23:4) upon which he leaned and kept himself erect. By the hand of God, out of straits and difficulties he reached a broad place, out of the dungeon of oppression to freedom, for Jahve had delighted in him, he was His chosen and beloved one. חפץ has the accent on the penult here, and Metheg as a sign of the lengthening (העמדה) beside the ē, that it may not be read ĕ.
(Note: In like manner Metheg is placed beside the ee of the final closed syllable that has lost the tone in חפץ Psalm 22:9, ותּחולל Psalm 90:2, vid., Isaiah S. 594 note.)
The following strophe tells the reason of his pleasing God and of His not allowing him to perish. This כּי חפץ בּי (for He delighted in me) now becomes the primary thought of the song.
