Charles H. Spurgeon on Psalms 49:4

I will incline mine ear to a parable. He who would have others hear, begins by hearing himself. As the minstrel leans his ear to his harp, so must the preacher give his whole soul to his ministry. The truth came to the psalmist as a parable, and he endeavoured to unriddle it for popular use; he would not leave the truth in obscurity, but he listened to its voice till he so well understood it as to be able to interpret and translate it into the common language of the multitude. Still of necessity it would remain a problem, and a dark saying to the unenlightened many, but this would not be the songster's fault, for, saith he, I will open my dark saying upon the harp. The writer was no mystic, delighting in deep and cloudy things, yet he was not afraid of the most profound topics; he tried to open the treasures of darkness, and to uplift pearls from the deep. To win attention he cast his proverbial philosophy into the form of song, and tuned his harp to the solemn tone of his subject. Let us gather round the minstrel of the King of kings, and hear the Psalm which first was led by the chief musician, as the chorus of the sons of Korah lifted up their voices in the temple.
