He will swallow up death in victory; and the Lord God will wipe away tears from off all faces; and the rebuke of his people shall he take away from off all the earth: for the Lord hath spoken it. Isaiah 25:8 KJV
"Porque ¿qué tiene el hombre de todo su trabajo, y de la fatiga de su corazón, con que se afana debajo del sol?." (Eclesiastes 2:22)
