Reference for Niddah 64:25

דברה תורה כלשון בני אדם

— Rather say: The law relating to a child who is nine years and one day old is traditional and the one relating to an infant one day old is derived from the Scriptural text. But, since the former is a traditional law, what was the purpose of the Scriptural text? — To exclude a woman from the uncleanness of a white discharge.
