Musar su Salmi 103:13

It seems to me that this is why Scripture says, “As a father has mercy upon his children” (Tehillim 103:13). Why is it not stated, “As a mother has mercy upon her children”? The answer is that it is the nature of a father who loves his children to discipline them, as it is stated, “One who spares the rod hates his son, but the one who loves him disciplines him every morning” (Mishlei 13:24). Every man who disciplines his son demonstrates thereby that he loves him, as is elaborated on in Midrash Rabbah, Parashas Shemos (1:1). A woman, on the other hand, is soft-hearted and does not wish for the father or teacher to strike the child. Moreover, while he is yet small the mother fulfills his every wish, granting him all his heart’s desires. Then when he becomes a youth he seeks out what he is accustomed to and eventually turns to evil ways. And all of this is caused by the woman.
