The 11th mitzvah is that we are commanded to study and to teach the wisdom of Torah. This is called Talmud Torah.

The source of this commandment is G‑d's statement,1 "Teach them to your children."

The Sifri says, "The phrase,2 'Teach them to your children,' refers to your students. One similarly finds all over that students are called children, as it is written,3 'And the children [i.e. the students] of the prophets went out.'"

Our Sages also said there, "The word,4 'Teach them,' signifies that they should be sharp in your mouth5; that when someone asks you something, you should not stammer, but rather answer him immediately."

This commandment is repeated numerous times: "Learn them,"6 "Do them,"7 "So that you will learn them."8 This commandment is stressed and encouraged in various passages spread throughout the Talmud.

Women are exempt from this commandment, since the verse says,9 "Teach your sons." Our Sages explain, "[This obligation applies to teaching] 'your sons,' and not your daughters," as explained in tractate Kidushin.10
