Charles H. Spurgeon on Psalms 119:37

Turn away mine eyes from beholding vanity. He had prayed about his heart, and one would have thought that the eyes would so surely have been influenced by the heart that there was no need to make them the objects of a special petition; but our author is resolved to make assurance doubly sure. If the eyes do not see, perhaps the heart may not desire: at any rate, one door of temptation is closed when we do not even look at the painted bauble. Sin first entered man's mind by the eye, and it is still a favourite gate for the incoming of Satan's allurements: hence the need of a double watch upon that portal. The prayer is not so much that the eyes may be shut as "turned away"; for we need to have them open, but directed to right objects. Perhaps we are now gazing upon folly, we need to have our eyes turned away; and if we are beholding heavenly things we shall be wise to beg that our eyes may be kept away from vanity. Why should we look on vanity? it melts away as a vapour. Why not look upon things eternal? Sin is vanity, unjust gain is vanity, self conceit is vanity, and, indeed, all that is not of God comes under the same head. From all this we must turn away. It is a proof of the sense of weakness felt by the Psalmist and of his entire dependence upon God that he even asks to have his eyes turned for him; he meant not to make himself passive, but he intended to set forth his own utter helplessness apart from the grace of God. For fear he should forget himself and gaze with a lingering longing upon forbidden objects, he entreats the Lord speedily to make him turn away his eyes, hurrying him off from so dangerous a parley with iniquity. If we are kept from looking on vanity we shall be preserved from loving iniquity.

And quicken thou me in thy way. Give me so much life that dead vanity may have no power over me. Enable me to travel so swiftly in the road to heaven that I may not stop long enough within sight of vanity to be fascinated thereby. The prayer indicates our greatest need, more life in our obedience. It shows the preserving power of increased life to keep us from the evils which are around us, and it, also, tells us where that increased life must come from, namely, from the Lord alone. Vitality is the cure of vanity. When the heart is full of grace the eyes will be cleansed from impurity. On the other hand, if we would be full of life as to the things of God we must keep ourselves apart from sin and folly, or the eyes will soon captivate the mind, and, like Samson, who could slay his thousands, we may ourselves be overcome through the lusts which enter by the eye.

This verse is parallel to Psalms 119:21, Psalms 119:29 in the previous eights: "rebuke, ""remove, ""turn away"; or "proud, ""lying, " "vanity."
