— But I still would say: If Vayomer, which was preceded by other mitzvoth, is included in "repetition," then the Ten Commandments, which was not preceded by other mitzvoth — how much more so should it be included in "repetition"! — No, this is refuted by "Vayomer," which, though it is not included in "binding" is included in "repetition." It is, therefore, written "And you shall repeat them to your sons." These (the aforementioned) are included in "repetition," and not the Ten Commandments.
"to your sons": These are your disciples. And thus do you find in all places, that disciples are called "sons," viz. (II Kings 2:3) "And the sons of the prophets came forth." Now were they the sons of the prophets? Were they not disciples? This shows that disciples were called "sons."
