Greek Wisdom - learning?

 Yerushalmi (Peah 01:01) They asked Rebbi Joshua: May a person teach Greek to his son? He said to them, he may teach him at an hour that is neither day nor night as it is written (Jos. 1:8): “You shall meditate about it day and night.” If it is so, a man would be forbidden to teach a profession to his son since it is written: “You shall meditate about it day and night.” But Rebbi Ismael stated (Deut. 30:19): “Choose life!” That refers to a profession. Rebbi Abba, son of Rebbi Ḥiyya bar Abba, Rebbi Ḥiyya in the name of Rebbi Joḥanan: Because of informants. Rebbi Abbahu in the name of Rebbi Joḥanan: A person may teach Greek to his daughter since it is an ornament for her. Simeon bar Abba heard that and said: Because he wants to teach his daughters, he attaches it to Rebbi Joḥanan. It should come over me if I ever heard it from Rebbi Joḥanan.
