He hath also prepared for him - The instruments of punishment are already prepared, and God can use them when he pleases. They are not to be made ready, and, therefore, there is no necessity for delay when he shall have occasion to use them. The idea is, that arrangements are made for the destruction of the wicked, and that the destruction must come upon them. The world is full of these arrangements, and it is impossible that the sinner should escape.
The instruments of death - The means of putting them to death; that is, of punishing them. The particular means referred to here are arrows, as being what God has prepared for the wicked. "Death" here is designed simply to denote punishment, as death would be inflicted by arrows.
He ordaineth his arrows against the persecutors - Or rather, as the Hebrew is, "He makes his arrows for burning," that is, "for burning arrows." Horsley renders it, "He putteth his arrows in action against those who are ready for burning." Prof. Alexander, "His arrows to (be) burning he will make." DeWette, "His arrows he makes burning." The Latin Vulgate and Septuagint, His arrows he has made for the burning: "that is, probably for those who are burning with rage, for persecutors. This seems to have been the idea of our translators. The Hebrew word - דלק dâlaq - means to burn, to flame; and hence, also, to burn with love, with anxiety, or with zeal or wrath - as persecutors do. But here the word seems properly to be connected with "arrows;" and the sense is, as rendered by Gesenius, "he maketh his arrows flaming;" that is, burning - alluding to the ancient custom of shooting ignited darts or arrows into besieged towns or camps, for the purpose of setting them on fire, as well as for the purpose of inflicting greater personal injury. The sense is, that God had prepared the means of certain destruction for the wicked. The reference here is not necessarily to persecutors, but what is said here pertains to all the wicked unless they repent.

He hath also prepared for him the instruments of death - This appears to be all a prophecy of the tragical death of Saul. He was wounded by the arrows of the Philistines; and his own keen sword, on which he fell, terminated his woful days!

He hath also prepared for him the instruments of death,.... The weapons of his indignation, Isaiah 13:5; which, will issue both in the first and second death, corporeal and eternal; the instruments of the former are diseases of various kinds, and judgments, as famine, pestilence, &c. and of the latter not only the law is an instrument of it, that being the letter which kills, and is the ministration of condemnation and death, but even the Gospel itself to wicked men is the savour of death unto death; and devils will be the executioners of it;
he ordaineth his arrows against the persecutors: the word for persecutors signifies "hot" or "burning" (h), and designs such persons who burn in malice and wrath, In rage and fury, against the saints, and hotly pursue after them, as Laban did after Jacob, Genesis 31:36; for these more especially God has determined in his eternal purposes and decrees, and for these he has provided in his quiver, arrows of wrath and vengeance, fiery ones; and against these will he bring them forth, direct them, and shoot them at them, Psalm 64:7. Some (i) understand all this not of God, but of the wicked man, and read "if he turn not", but, on the contrary, instead of that, "will whet his sword, bend his bow", &c. against the righteous; yet he shall be disappointed, he shall not accomplish his designs, as appears by the following verses; these phrases are used of wicked men, Psalm 11:2, but the former sense seems best.
(h) "ardentibus", V. L. "in ardentes", Montanus; "hot persecutors", Ainsworth. (i) So Brentius & Glassius in Gejerus.

against the persecutors--Some render "for burning," but the former is the best sense. Arrows for burning would be appropriate in besieging a town, not in warring against one man or a company in open fight.

Him - For the wicked. Ordaineth - Designs or fits for this very use. Of all sinners, persecutors are set up as the fairest marks of Divine wrath. They set God at defiance but cannot set themselves out of the reach of his judgments.
