Charles H. Spurgeon on Psalms 119:123

Mine eyes fail flor thy salvation. In times of great sorrow when the heart is oppressed with care, and when danger threatens on every side, the human eye expresses with amazing accuracy the distressed and anguished emotions of the soul. The posture here described is that of an individual who perceives himself surrounded with enemies of the most formidable character, who feels his own weakness and insufficiency to enter into conflict with them, but who is eagerly looking for the arrival of a devoted and powerful friend who has promised to succour him in the hour of his calamity. As his friend delays the hour of his coming, his fears and anxieties multiply, till he finds himself in the condition of one whose eyes fail and grow dim in looking for the approach of his great deliverer. In this condition was the suppliant here described, his enemies were ready to swallow him up, and except from heaven he had no hope of final extrication. To the promises of God he betook himself, and while waiting their accomplishment, and looking with the utmost eagerness to the word of God's righteousness, he gives utterance to the desponding sentiment, "Mine eyes fail for thy salvation." O for such warm and anxious desires for that great salvation, which will realize the victory over all our spiritual enemies, and enable us to shout triumphantly through all eternity in the name of our almighty Deliverer! John Morison.
