יג אמר רבא אף אנן נמי תנינא (במדבר יט, יז) ונתן עליו מים חיים אל כלי שתהא חיותן בכלי ונתן אלמא תלושין נינהו והא מחוברין נינהו

Rashi: 'And he shall put' implies that Scripture refers to detached water, i.e., water which does not form part of a stream but has been detached and collected in a vessel, whence it is poured into a second vessel containing the ashes. But when the Mishnah states that the running must be direct into the vessel, it insists on attached water, i.e., water forming part of the stream. This must be because the Rabbis set a higher standard. Tosaf.: 'and he shall put' implies that the water is regarded as detached water, which can be defiled, though actually it is running water, as stated, and consequently this proves that by Scriptural law sacred water cannot be made clean by 'levelling' (v. p. 158, n. 4) . for levelling only renders it as attached water, whereas we see here that even when attached it is regarded as detached. And just as Scripture thus sets a higher standard for sacred water, so did the Rabbis set a higher standard for terumah. - Maharsha observes');"><sup>38</sup></span>
