Charles H. Spurgeon on Psalms 119:154

Plead my cause, and deliver me, etc. He now supposes himself to be arraigned before the tribunal of men, as he certainly was in their general charges against him; arraigned, too, in his helplessness, without a name, without state; in such way as one disowned would be arraigned. He prays the Lord to come in and plead his cause; so should he be redeemed; for this is the import of the original. As it were, he regards himself as one sold to corrupt judges, or at all events, as one that has lost his standing in society in the estimation of men. But if the Lord will come, and maintain the cause of his servant, his servant shall be redeemed indeed. There is good confidence in this prayer; the man of God is acquainted with the way of the Lord, and he makes his believing application. O how much do we need to know the Lord's righteous character in our seasons of great distress! Now the Lord pleads the cause of his own by the power of the truth; he pleads it also in his providences of divers kinds; he acts upon the hearts, and the hopes, and the fears of men; and in many wondrous ways he pleads his people's cause. He redeems his saints from all evil; and if not together from all evil in this world, certainly from all evil as concerns the world to come. John Stephen.
