For all his days are sorrows; or, though all his days were sorrows, i.e. full of sorrows. For this seems added to aggravate the evil mentioned in the foregoing verse. Though he took great and unwearied pains all his days, yet after death he hath no more benefit by it than another man hath. His travail grief; the toils of his body are, or were, accompanied with the vexations of his mind. Taketh not rest in the night; either because his mind is distracted, or his sleep broken, with perplexing cares and fears.
