Eclesiastés 12

Meu filho, fica ciente também disto: a escrita de muitos livros não tem limite, e o muito estudar traz cansaço ao corpo.

Ahora, hijo mío, á más de esto, sé avisado. No hay fin de hacer muchos libros; y el mucho estudio aflicción es de la carne.

And further, by these, my son, be admonished: of making many books there is no end; and much study is a weariness of the flesh.

Furthermore, my son, be admonished: of making many books there is no end; and much study is a weariness of the flesh.
