אֲנִי אֶת נַפְשִׁי הִצַּלְתִּי
Definition (Hebrew)
בְּהַשְׁאָלָה: אֶת עַצְמִי הִסְפַּקְתִּי לְהַצִּיל וְלֹא מְעַנְיֵן אוֹתִי הַשְּׁאָר. הַבָּעַת חֹסֶר אִכְפַּתִּיּוּת לְגוֹרַל הַזּוּלָת.
("וְאַתָּה כִּי הִזְהַרְתּוֹ צַדִּיק לְבִלְתִּי חֲטֹא צַדִּיק וְהוּא לֹא חָטָא חָיוֹ יִחְיֶה כִּי נִזְהָר וְאַתָּה אֶת נַפְשְׁךָ הִצַּלְתָּ"- יְחֶזְקֵאל ג כא)
