Charles H. Spurgeon on Psalms 55:4

My heart is sore pained within me. His spirit writhed in agony, like a poor worm; he was mentally as much in pain as a woman in travail physically. His inmost soul was touched; and a wounded spirit who can bear? If this were written when David was attacked by his own favourite son, and ignominiously driven from his capital, he had reason enough for using these expressions. And the terrors of death are fallen upon me. Mortal fears seized him, he felt like one suddenly surrounded with the glooms of the shadow of death, upon whom the eternal night suddenly descends. Within and without he was afflicted, and his chief terror seemed to come from above, for he uses the expression, "Fallen upon me." He gave himself up for lost. He felt that he was as good as dead. The inmost centre of his nature was moved with dismay. Think of our Lord in the garden, with his "soul exceeding sorrowful even unto death, " and you have a parallel to the griefs of the psalmist. Perchance, dear reader, if as yet thou hast not trodden this gloomy way, thou wilt do soon; then be sure to mark the footprints of thy Lord in this miry part of the road.
