All nations compassed me In these verses he relates the wonderful deliverance which he had received, that all might know that it was not of human but divine origin. Once and again he declares, that he was compassed not by a few persons, but by a vast multitude. The people, being all inflamed with anger and fury against him, compassed him so that there were no means for his escape, and he could procure help from no quarter but from heaven. Some consider his complaint, that all nations were adverse to him, as referring to the neighboring nations, by whom we know David was surrounded with danger. His meaning, in my opinion, is, that the whole world was adverse to him; because he places God's help alone in opposition to the deadly and furious hatred both of his own countrymen and of the neighboring nations towards him, so that there was not a spot upon the earth where he could be safe. There was, it is true, no army, collected from several nations, besieging him; still he had no peaceable retreat except among the haunts of wild beasts, from which also he was driven by terror. And in proportion to the number of persons he encountered were the snares laid to entrap him. It is, therefore, not wonderful that he said he was compassed by all nations. Besides, this elliptical mode of speaking is more forcible than if he had merely said that he trusted in God, by reason of which he had become victorious. By publicly mentioning the name of God alone, he maintains that no other means of deliverance were within his reach, and that but for his interposition he must have perished. It appears to me preferable to translate the particle ky, ki, affirmatively. [1] "Besieged as I am on all sides by the world, yet if the power of God help me, that will be more than adequate for the extermination of all mine enemies." Their obstinate and implacable hatred is pointed out by him in the repetition of the phrase compassed about, and their outrageous fury is set forth in comparing them to bees, which, though not possessed of much strength, are very fierce, and when in their insensate fury they attack a person, they occasion no little fear. He shortly adds, they are quenched as a fire of thorns, which at first makes a great crackling, and throws out a greater flame than a fire of wood, but soon passes away. The amount is, that David's enemies had furiously assailed him, but that their fury soon subsided. Hence he again repeats, that sustained by the power of God, whatever opposition might rise against him would soon pass away.

1 - "I take ky to be an affirmative adverb, surely, and not a conjunction." -- Lowth.

All nations compassed me about - They surrounded me; they hemmed me in on every side, so that I seemed to have no chance to escape. It would seem from this that the psalm was composed by someone who was at the head of the government, and whose government had been attacked by surrounding nations. This would accord well with many things that occurred in the life of David; but there were also other times in the Jewish history to which it would be applicable, and there is nothing that necessarily confines it to the time of David.
But in the name of the Lord will I destroy them - Margin, as in Hebrew," cut them off." This is the language which he used at that time; the purpose which he then formed; an expression of the confidence which he then cherished. He meant to subdue them; he had no doubt that he would be able to do it.

All nations compassed me about - This is by some supposed to relate to David, at the commencement of his reign, when all the neighboring Philistine nations endeavored to prevent him from establishing himself in the kingdom. Others suppose it may refer to the Samaritans, Idumeans, Ammonites, and others, who endeavored to prevent the Jews from rebuilding their city and their temple after their return from captivity in Babylon.
But in the name of the Lord will I destroy them - Dr. Kennicott renders אמילם amilam, "I shall disappoint them;" Bishop Horsley, "I cut them to pieces;" Mr. N. Berlin, repuli eas, "I have repelled them." "I will cut them off;" Chaldee. Ultus sum in eos, "I am avenged on them;" Vulgate. So the Septuagint.

All nations compassed me about,.... Not all the nations of the world, but all the neighbouring nations about Judea; as the Philistines, Moabites, Ammonites, Amalekites, and Syrians; and these not all at one time, but sometimes one, and sometimes another, whom David fought with and subdued: and these, applied to Christ, design Herod and Pontius Pilate, with the Gentiles and the people of Israel; who were gathered together against him, to do what God had determined should be done, Acts 4:27; see Psalm 22:12. And this is sometimes the case of the church and people of God: at the first setting up of the interest of Christ, the whole world was against it; and in such circumstances was the church of Christ, when the whole world wondered after the beast, the Romish antichrist; as it will be when the kings of the earth and of the whole world will be gathered to the battle at Armageddon; and also when the Gog and Magog army shall compass the camp of the saints and the beloved city; see Revelation 13:3; and so Jarchi interprets this of Gog and Magog. Yea, it is applicable to particular believers, who are attacked by Satan, the god of this world; and who are hated and persecuted by the men of it in general; and who are beset on all hands, at times, with the temptations of the devil, and the corruptions of their own hearts, and the snares of the world; that it is as if all nations compassed them about;
but in the name of the Lord will I destroy them; that is, calling upon the name of the Lord; as Asa, Jehoshaphat, and others did besides David: or trusting in the name of the Lord; and so the Targum,
"in the name of the Word of the Lord I trusted, therefore will I cut them off.''
Or, going forth in the name and strength of the Lord, as David did against Goliath; and so against all nations that gathered together against him, whose armies he vanquished and destroyed, and made the nations tributary to him. Thus our Lord Jesus Christ, his antitype, as Mediator stood in the strength and in the majesty of the name of the Lord, calling upon him to glorify him; and, trusting in his help and power, he attacked all his and our enemies, and obtained an entire victory over them, to the utter demolition of them; sin, Satan, the world, death, and hell. The word (u) used has the signification of concision or circumcision; and may have a peculiar regard to the Jews, who boasted of their circumcision, and were the implacable enemies of Christ; and who were destroyed by him, when wrath came upon them to the uttermost.
(u) "concidebam eos", Piscator; "concidam eos", Schmidt.

Though as numerous and irritating as bees [Psalm 118:12], by God's help his enemies would be destroyed.

Nations - The neighbouring nations, Philistines, Syrians, Ammonites, Moabites, who were stirred up, by the overthrows which David had given some of them, by their jealousy at his growing greatness, and by their hatred against the true religion.
