R' Tzadok testified concerning the brine of nonkosher grasshoppers that it is tahor, because the earlier Mishnah [had stated]: “Nonkosher grasshoppers that were pickled together with kosher grasshoppers do not render their brine forbidden.”

R' Tzadok testified concerning where [the] flowing [waters] are greater than the trickling [waters], that they are valid. There was an incident in Biras HaPilya, and the incident was brought before the Sages and they ruled [the mingled wa-ter] fit.
