their hands over the heifer that is beheaded in the valley: in token of their innocence, and this they did not only for themselves, but for the whole city, being the representatives of it; see Psa 26:6 . Some think that this is a confirmation of the sense embraced by some, that it was a strong stream to which the heifer was brought; and there might be a stream of water here, and a valley also; though it would be no great difficulty to get from the city, which was near, a sufficient quantity of water to wash the hands of the elders with. This may denote the purification of sin by the blood of Christ, when it is confessed over him; and shows that priests and elders, ministers of the word, as well as others, stand in need of it; and that even those concerned in the death of Christ shared in the benefits of it.
