Then that teacher smote the child on the head and when the child received the blow, he said unto him: I ought to teach thee and not thou to teach me. I know the letters which thou wouldest teach me, and I know that ye are unto me as vessels out of which cometh nought but sound, and neither wisdom nor salvation of the soul. And beginning the line he spake all the letters from A even unto T fully with much quickness: and he looked upon the master and said: But thou knowest not how to interpret A and B: how wouldest thou teach others? Thou hypocrite, if thou knowest and canst tell me concerning A, then will I tell thee concerning B. But when the teacher began to expound concerning the first letter, he was not able to give any answer.
