Charles H. Spurgeon on Psalms 119:19

Hide not thy commandments from me. The manner of David's reasoning is this. I am here a stranger and I know not the way, therefore, Lord, direct me. The similitude is taken from passengers, who coming to an uncouth country where they are ignorant of the way, seek the benefit of a guide. But the dissimilitude is here: in any country people can guide a stranger to the place where he would be; but the dwellers of the earth cannot show the way to heaven; and therefore David seeks no guide among them, but prays the Lord to direct him. William Cowper.
