For all his days are sorrows, and his travail grief; yea, his heart taketh not rest in the night. This is also vanity.
All his days are sorrows and his travail grief. Same sentiment as Ecclesiastes 2:21, interrogatively. The only fruit he has is, not only sorrows in his days, but "all his days are sorrow and his travail" (not only has griefs connected with it, but is itself) "grief."
