These verses serve to illustrate the subject of the whole Psalm, in reference to the occasion on which it is supposed to have been written. If it relates to the destruction of Sennacherib's army in the night, by the destroying angel, the circumstance is here mentioned in great beauty of language. But we may without violence, and indeed with much improvement, consider the spiritual sense of it as relating to the sovereignty of God over sinners. How often doth the Lord, arrest them in their course, and convert the very weapons they were bringing forth against himself and his people, as means in his almighty hand for the promotion of his glory? See that illustrious instance in point of Paul's conversion, Acts 9:1.
