Ezek 3:18

בְּאָמְרִ֤י לָֽרָשָׁע֙ מ֣וֹת תָּמ֔וּת וְלֹ֣א הִזְהַרְתּ֗וֹ וְלֹ֥א דִבַּ֛רְתָּ לְהַזְהִ֥יר רָשָׁ֛ע מִדַּרְכּ֥וֹ הָרְשָׁעָ֖ה לְחַיֹּת֑וֹ ה֤וּא רָשָׁע֙ בַּעֲוֺנ֣וֹ יָמ֔וּת וְדָמ֖וֹ מִיָּדְךָ֥ אֲבַקֵּֽשׁ׃

If I say to the wicked man, ‘You will surely die,’ but you do not warn him or speak out to warn him from his wicked way to save his life, that wicked man will die in his iniquity, and I will hold you responsible for his blood.
