Musar על סוטה 82:6

A man should undergo danger rather than be guilty of this sin. And our Sages, of blessed memory, said, concerning Agrippas, that when he was reading the Torah and came to the verse, "Thou mayest not put a foreigner over thee, who is not thy brother" (Deut. 17:15), his eyes shed tears. Those who were near him said, "Do not fear Agrippas. You are our brother." In that hour the "enemies of Israel" [a euphemism for the "Chidren of Israel" where anything dire is said concerning them] became liable to destruction for they flattered Agrippas (Sotah 41a-b).
