What is the meaning of "Notzer Torah Ben Mevin"?
Malbim: A son who understands does not go after gluttony and desires. He guards Torah, which muzzles desires.
Who is "Ro'eh Zolelim"?
Rashi: He joins to himself gluttons. Ro'eh is an expression of Re'im (friends).
Malbim: It is a son who veers from the way of Torah. He joins with gluttons. He shames the one who fathered him. It would have been better had he not come to the world. The Torah testified about him that in the end, he will rob people 1 .
He refers to Ben Sorer u'Moreh. Chazal (Sanhedrin 72a) said that the Torah commands to kill him, for in the end he will rob people. That is only for one who twice stole from his father, and ate meat and drank quality wine! (PF)
