בְּ֭הִשָּׁ֣פְטוֹ יֵצֵ֣א רָשָׁ֑ע וּ֝תְפִלָּת֗וֹ תִּהְיֶ֥ה לַֽחֲטָאָֽה׃
Rechtet er, so geh er schuldig aus, und sein Gebet werde zur Sünde.
Jerusalem Talmud Shabbat
Rebbi Ayvo bar Nagori. It is written198Ps. 109:7., when he will be judged he will be found guilty. It is not written “he will be justified” but when he will be judged he will be found guilty. But from here that Satan accuses only in times of danger.
