וְיָצְא֥וּ זְקֵנֶ֖יךָ וְשֹׁפְטֶ֑יךָ וּמָדְדוּ֙ אֶל־הֶ֣עָרִ֔ים אֲשֶׁ֖ר סְבִיבֹ֥ת הֶחָלָֽל׃
너의 장로들과 재판장들이 나가서 그 피살한 곳에서 사면에 있는 각 성읍의 원근을 잴 것이요
Sifrei Devarim
(Devarim 21:6) "And all the elders of that city": Even if they are a hundred. Because we said above ([21:2] re the measuring), three or five, I might think that this is so here, too. (in respect to the washing of the hands); it is, therefore, written "and all the judges of that city" — even if they are a hundred.
