The Rule of Our Most Holy Father Saint Benedict · Chapter XLV.

Of those who commit any fault in the Oratory.

If any one, while reciting a psalm, responsory, antiphon, or lesson, shall make any mistake and not forthwith for it before all, let him be liable to greater punishment, as one who will not correct by humility, what he hath done amiss through negligence. But for such a fault, let children be beaten.
