Mischna zu Amos 4:13

Yose ben Yochanan (a man) of Jerusalem used to say: Let thy house be wide open, and let the poor be members of thy household. Engage not in too much conversation with women. They said this with regard to one’s own wife, how much more [does the rule apply] with regard to another man’s wife. From here the Sages said: as long as a man engages in too much conversation with women, he causes evil to himself, he neglects the study of the Torah, and in the end he will inherit gehinnom.
