John Gill Bible Commentary

Cast forth lightning, and scatter them,.... The mountains, the kings and kingdoms of the earth; the enemies of David, and of Christ, and of his people; particularly the Jews, who have been scattered all over the earth by the judgments of God upon them; cast forth like lightning, which is swift, piercing, penetrating, and destructive; shoot out thine arrows, and destroy them; or, "trouble them" (k); as the Targum, Septuagint, and Arabic versions, nearer to the Hebrew: these also design the sore judgments of God, the arrows of famine, pestilence, and sword; which fly swiftly, pierce deeply, cut sharply, and, like fiery darts, give great pain and trouble. So Kimchi and Ben Melech interpret them of the decrees which come down from heaven, as Aben Ezra does Psa 144:5, by "lightning" Arama understands the flame of fire which comes out with thunder; and by "arrows" the thunderbolt, which he calls a stone hardened in the air like iron. (k) "ac turba eos", Tigurine version; "et conturba eos", Cocceius, Michaelis.
