Ben Sira 38:28-34

28 So too is the smith sitting by the anvil, intent upon his handiwork in iron; the breath of the fire melts his flesh, and he wastes away in the heat of the furnace; he inclines his ear to the sound of the hammer, and his eyes are on the pattern of the object. He sets his heart on finishing his handiwork, and he is careful to complete its decoration.
29 So too is the potter sitting at his work and turning the wheel with his feet; he is always deeply concerned over his work, and all his output is by number.
30 He moulds the clay with his arm and makes it pliable with his feet; he sets his heart to finish the glazing, and he is careful to clean the furnace.
31 All these rely upon their hands, and each is skilful in his own work.
32 Without them a city cannot be established, and men can neither sojourn nor live there.
33 Yet they are not sought out for the council of the people, nor do they attain eminence in the public assembly. They do not sit in the judge's seat, nor do they understand the sentence of judgment; they cannot expound discipline or judgment, and they are not found using proverbs.
34 But they keep stable the fabric of the world, and their prayer is in the practice of their trade.
