The [passage regarding the] decapitated calf [must be recited] in the Holy Tongue, as it is said (Deut. 21:1): If a corpse should be found, in the land ...  Your elders and your judges shall go out (ibid. 21:2) —- three [members] of the High Court in Jerusalem would go out. R’ Yehudah says: Five; as it is said, your elders —- two, and your judges —- [another] two, and [since] a court cannot be even, they add one more.
