Charles H. Spurgeon on Psalms 18:14

"He shot out his lightnings." (Heb.) LXX astrapus eplhyune. Falgura multiplicavit: Vulgate, and so all the versions. He multiplied his thunderbolts; or, shot them out thick one after another; as the word properly signifies. (Heb.) And discomfited them, as we render the word; or rather, as I think it should be translated, and melted them; namely, the heavens. —Samuel Chandler.

Verse 14 (last clause). It is written, "destroyed them," because the Holy Ghost would not so much as name, by the mouth of his prophet, the evil spirits to whom he refers. —Euthymius Zigabenus (1125) quoted by J. M. Neale.
