28. Similarly, every craftsman and artisan, who crafts in the night as well as in the day, who sculpts graven seals, and who, by his diligence, varies the image, will give his mind over to the likeness of the image. And he will complete the work by his vigilance.
29. The blacksmith, sitting by his anvil and considering a work of iron, is similar. The steam from the fire singes his flesh, and he struggles against the heat of the furnace.

31. He gives his heart to the completion of his work, and his vigilance adorns it to perfection.
