Psalms 55:4 - Joseph Benson’s Commentary on the Old and New Testaments

My heart is sore pained within me Hebrew, יחיל, jachil, trembles, or suffers pains like those of a travailing woman, as the word properly signifies. My heart, which hath generally supported me in my distresses, is now ready to sink within me; therefore, Lord, pity and help me. The terrors of death are fallen upon me Either deadly terrors, such as seize upon men in the agonies of death, or fear of death; which is the more grievous to me, because my death would reflect dishonour upon thee, and bring many miseries upon the people.
