Father – The obligation of a father to educate and reprimand his children:^[1]

The obligation to educate a child in Torah and mitzvah’s is specifically upon the father of the child. He is obligated to educate both his son and daughter in the negative and positive commands, and is likewise required to reprimand his child and stop him from performing any transgression.

If the father does not reprimand his child:[2] If the father does not reprimand his child from transgressing a Biblical command, then the father himself is to be reprimanded by the Beis Din. However, for not stopping his children from transgressing Rabbinical commands the father does not need to be chastised.
