Psalms 55:18 - Joseph Benson’s Commentary on the Old and New Testaments

He hath delivered my soul He may be considered, either as referring to former deliverances, and mentioning them as a reason why he should now trust in God; or as speaking of a future deliverance as already effected, because he was confident it would be effected. He adds, in peace, because he was persuaded God would restore him to his former peace and tranquillity. But, perhaps, he speaks of inward peace, peace of soul. By patience and trusting in God, he kept possession of his peace, in the midst of the tumult, clamour, and confusion, yea, and the bloodshed and slaughter attending the rebellion. For there were many with me David thought, at first, almost all were against him, but now he sees there were many with him, more than he imagined; his interest proved better than he expected, and of this he gives God the glory. For it is he that raiseth us up friends when we need them, and makes them faithful to us. There were many with him; for though his subjects in general deserted him, and went over to Absalom; yet God was with him, and the good angels. With an eye of faith he now sees himself surrounded, as Elisha was, with chariots of fire, and horses of fire, and, therefore, triumphs thus: There are many with me, more with me than against me, 2 Kings 6:16-17.
