Then thy elders and thy judges shall come forth,.... From the city or cities near to which the murder was committed, to make inquiry about it, and expiation for it; so Aben Ezra interprets it of the elders of the cities near, but others understand it of the elders of the great sanhedrim at Jerusalem; so the Targum of Jonathan,"then shall go out from the great sanhedrim two of thy wise men, and three of thy judges;''and more expressly the Misnah ,"three go out from the great sanhedrim in Jerusalem;''R.
Judah says five,"it is said "thy elders" two, and "thy judges" two,''and there is no sanhedrim or court of judicature equal (or even), therefore they add to them one more:and they shall measure unto the cities which are round about him that is slain; that is, from the place where the slain lies, as Jarchi rightly interprets it; on all sides of it, from the four corner's, as the Targum of Jonathan, the cities round about the slain.
Maimonides says, they do not behead the heifer for, nor measure, but to a city in which there is a sanhedrim: if it is found between two cities (that is, at an equal distance), both bring two heifers (Maimonides says they bring one between them, which is most reasonable); but the city of Jerusalem does not bring an heifer to be beheaded: the reason is, because it was not divided to the tribes .
This measuring, one would think, should be only necessary when it was not certain which was the nearest city; and yet Maimonides says, even when it was found on the side of a city, which was certainly known to be nearest, they measured; the command, he observes, is to measure.
