Charles H. Spurgeon on Psalms 27:9

Hide not thy face far from me. The word "far" is not in the original, and is a very superfluous addition of the translators, since even the least hiding of the Lord's face is a great affliction to a believer. The command to seek the Lord's face would be a painful one if the Lord, by withdrawing himself, rendered it impossible for the seeker to meet with him. A smile from the Lord is the greatest of comforts, his frown the worst of ills. Put not thy servant away in anger. Other servants had been put away when they proved unfaithful, as for instance, his predecessor Saul; and this made David, while conscious of many faults, most anxious that divine long suffering should continue him in favour. This is a most appropriate prayer for us under a similar sense of unworthiness. Thou hast been my help. How truly can we join in this declaration; for many years, in circumstances of varied trial, we have been upheld by our God, and must and will confess our obligation. "Ingratitude, "it is said, "is natural to fallen man, "but to spiritual men it is unnatural and detestable. Leave me not, neither forsake me. A prayer for the future, and an inference from the past. If the Lord had meant to leave us, why did he begin with us? Past help is but a waste of effort if the soul now be deserted. The first petition, "leave me not, "may refer to temporary desertions, and the second word to the final withdrawal of grace, both are to be prayed against; and concerning the second, we have immutable promises to urge. O God of my salvation. A sweet title worthy of much meditation.
