לֹא־תֵלֵ֤ךְ רָכִיל֙ בְּעַמֶּ֔יךָ לֹ֥א תַעֲמֹ֖ד עַל־דַּ֣ם רֵעֶ֑ךָ אֲנִ֖י יְהוָֽה׃
Janganlah engkau berkeliling menyebarkan fitnah di antara bangsamu; janganlah engkau berdiam diri ketika nyawa sesamamu terancam. Akulah Yang Mahakekal.
Sanhedrin
Our Rabbis taught [in a baraita]: From where do we learn that one who chases after his friend to kill him may be saved [at the expense] of his life? The Torah says [Leviticus 19:16], "Do not stand by the blood of your neighbor." You're right! [the passuk is unavalibe to be used here]
