Charles H. Spurgeon on Psalms 49:2

Both low and high, rich and poor, together. Sons of great men, and children of mean men, men of large estate, and ye who pine in poverty, ye are all bidden to hear the inspired minstrel as he touches his harp to a mournful but instructive lay. The low will be encouraged, the high will be warned, the rich will be sobered, the poor consoled, there will be a useful lesson for each if they are willing to learn it. Our preaching ought to have a voice for all classes, and all should have an ear for it. To suit our word to the rich alone is wicked sycophancy, and to aim only at pleasing the poor is to act the part of a demagogue. Truth may be so spoken as to command the ear of all, and wise men seek to learn that acceptable style. Rich and poor must soon meet together in the grave, they may well be content to meet together now. In the congregation of the dead all differences of rank will be obliterated, they ought not now to be obstructions to united instructions.
