Halakhah su Deuteronomio 21:2

And this commandment is practiced in the Land of Israel at the time when it is in its inhabitation, and also in Transjordan. And its obligation is upon the males and especially upon the great men of the city; and like the matter that is written (Deuteronomy 21:3), "and the elders of that city." And that which Scripture states first (Deuteronomy 21:2), "And your elders and your judges will go out," is speaking about the elders of Jerusalem. As so did they, may their memory be blessed, say (Sotah 44b) that five elders of the Great Court in Jerusalem would go out and measure. And upon them is the commandment of measurement; but upon the elders of the city is the commandment of the calf, of the washing of the hands and of the reciting of those verses, as it is stated (Deuteronomy 21:2), "Our hands did not spill this blood, and our eyes did not see" - meaning to say, the one killed did not come to 'our hands' and we dispatched him without provisions; and 'our eyes did not see him' leave our city and we dispatched him without escort (Sotah 45b).
