Sirach 38:29-31

New Revised Standard Version, Anglicised Catholic Edition

²⁹ So it is with is the potter sitting at his work
    and turning the wheel with his feet;
he is always deeply concerned over his products,
    and he produces them in quantity.
³⁰ He moulds the clay with his arm
    and makes it pliable with his feet;
he sets his heart on finishing the glazing,
    and he takes care in firing^[a] the kiln.
