The Chasam Sofer responds to Rabbi Tzvi Hirsch Chajes' work Toras Nevi'im with detailed comments on the authority of kings, prophets, and communal bans. He argues that royal execution authority derives from the people's cherem-oath to Yehoshua, that lo bashamayim hi safeguards Torah integrity against false prophetic claims, and that fast days serve teshuvah rather than mere mourning.
