5. Mose (Dewarim) 21:2

ויצאו זקניך THEN THE ELDERS [AND THE JUDGES] SHALL GO FORTH — i.e. the distinguished amongst thy elders, these are the Great Sanhedrin (Sotah 44b). ומדדו AND THEY SHALL MEASURE — from the place where the corpse lies, אל הערים אשר סביבת החלל UNTO THE CITIES WHICH ARE ROUND ABOUT HIM THAT IS SLAIN — in every direction, in order to ascertain which is the nearest.

then thy elders and thy judges shall come out, and they shall measure to the cities which are round about him that is slain:

וְיָצְא֥וּ זְקֵנֶ֖יךָ וְשֹׁפְטֶ֑יךָ וּמָדְדוּ֙ אֶל־הֶ֣עָרִ֔ים אֲשֶׁ֖ר סְבִיבֹ֥ת הֶחָלָֽל׃
