Do not kill a murderer before he stands trial

'The cities shall be to you as a refuge from the avenger, so that the manslayer will not die until he stands before the congregation for trial.

Hebrew

יב וְהָיוּ לָכֶם הֶעָרִים לְמִקְלָט, מִגֹּאֵל; וְלֹא יָמוּת הָרֹצֵחַ, עַד-עָמְדוֹ לִפְנֵי הָעֵדָה לַמִּשְׁפָּט.

Greek

12 καὶ ἔσονται αἱ πόλεις ὑμῖν φυγαδευτήρια ἀπὸ ἀγχιστεύοντος τὸ αἷμα, καὶ οὐ μὴ ἀποθάνῃ ὁ φονεύων, ἕως ἂν στῇ ἔναντι τῆς συναγωγῆς εἰς κρίσιν.
