Commentators explain that David's distress was not just emotional but profoundly physical. His cry that his 'eye, soul, and body' are wasting away illustrates how deep sorrow can impact every part of a person—from vision blurred by tears to a weakened spirit and physical exhaustion. Scholars like Ellicott and Barnes note this holistic suffering, reminding believers that God understands when their spiritual anguish manifests in bodily ways.
