Sirach 38:29-31

Revised Standard Version Catholic Edition

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.
