Didache 7:1

Patristic

1 Concerning baptism, baptise thus: Having first rehearsed all these things, baptise, in the Name of the Father and of the Son and of the Holy Ghost, in running water; 2 But if thou hast no running water, baptise in other water, and if thou canst not in cold, then in warm. 3 But if thou hast neither, pour water three times on the head in the Name of the Father, Son and Holy Ghost. 4 And before the baptism let the baptiser and him who is to be baptised fast, and any others who are able. And thou shalt bid him who is to be baptised to fast one or two days before. Source

Mishnah Mikvaot 1:8

Rabbinic (Mishnah)

Superior to such [water] is [the water of] the mikveh containing forty seahs, for in it people may immerse themselves and immerse other [things]. Superior to such [water] is [the water of] a spring whose own water is little but has been increased by a greater quantity of drawn water. It is equivalent to the mikveh in as much as it may render clean by standing water, and to an [ordinary] spring in as much as one may immerse in it whatever the quantity of its contents. Superior to them are "smitten waters" which can purify even when flowing [on the ground]. Superior to them are "living waters" for in them there is immersion for zavim and sprinkling for metzoraim, and they are valid for the preparation of the hatat waters. Source
