Psalms 64:7

“But God shall shoot at them [with] an arrow, etc.] With one or other of his four judgments; famine, pestilence, sword, and wild beasts, (<261421>Ezekiel 14:21); which he brings upon wicked men; and may be compared to arrows, as they are, (<260516>Ezekiel 5:16,17 <199105>Psalm 91:5,6 <053241> Deuteronomy 32:41,42); because they move swiftly. The judgment of wicked men lingereth not, though it may seem to do so; and because they often come suddenly and at an unawares, when men are crying Peace, peace; and because they are sharp and piercing, penetrate deep and stick fast, and wound and kill; they are not arrows of deliverance, unless to the Lord’s people, who, by his judgments on the wicked,…”

“The contrast is heightened by representing God as using weapons like theirs.”

“But God shall shoot at them with an arrow - That is, Instead of their being able to carry out their purposes of shooting the arrows which they had prepared against others, God will shoot his arrows against them. The tables will be turned. They themselves will experience what they had intended to inflict on others. God will deal with them as they intended to deal with others. The sentiment here is substantially the same as in Psalms 7:15; see the notes at that passage. It is also in accordance with what we often find in the writings of David, when in the close of a psalm he expresses a confident expectation that the prayer which he had offered in the beginning would be heard, or rejoices in…”

“64:7-10 What God does is righteous. God undoes what is wicked and pays the wicked back with what they planned for others.”

“God: Psa 7:12, Psa 7:13, Psa 18:14; Deu 32:23, Deu 32:42; Job 6:4; Lam 3:12, Lam 3:13 suddenly: Psa 64:4, Psa 73:19; Pro 6:15, Pro 29:1; Isa 30:13; Mat 24:40, Mat 24:50, Mat 24:51; Th1 5:2, Th1 5:3 shall they be wounded: Heb. their wound shall be, Kg1 22:34; Ch1 10:3-7 Psalms 64:8”

“Deep is man's heart and inward part, but not too deep for God, who knoweth the heart ( Jer 17:9.). And He will just as suddenly surprise the enemies of His anointed with their death-blow, as they had plotted it for him. The futt. consec. that follow represent that which is future, with all the certainty of an historical fact as a retribution springing from the malicious craftiness of the enemies. According to the accentuation, Psa 64:8 is to be rendered: "then will Elohim shoot them, a sudden arrow become their wounds." Thus at length Hupfeld renders it; but how extremely puzzling is the meaning hidden behind this sentence! The Targum and the Jewish expositors have construed it differently:…”
