Psalms 119:18 - Coke's Commentary on the Holy Bible

Open thou mine eyes— That is, "Illuminate the eyes of my mind by thy grace, that I may clearly discern the admirable wisdom hidden in thy law;" for the Hebrew word נפלאות niphlaoth, rendered wondrous things, signifies hidden wonders. The distressed circumstances of the Psalmist, when compared with the magnificent promises made in the law to the righteous, might fill him with perplexity; and as he was unable to reconcile his condition with the letter of the law, he might possibly address God for illumination in this point, which was to him otherwise inexplicable, and, what he elegantly stiles it, a hidden wonder. See Mr. Boyle on the Stile of the Sacred Scripture. I am a stranger in the earth, in the next verse, would be better rendered, I am a stranger in the land, as being forced to wander from place to place. See 1 Samuel 23:13.
