Which book in the Torah addresses the commandement of Mikveh?

Question

i.e., Genesis...Leviticus, etc.

Answer 1

The most references seem to be in Leviticus, but you'll also see references to mikveh in other books.

Here's a link to references to them all:

Answer 2

I have never seen it in the Torah specifically stating immersion. Only cleansing. I think it may be in the Talmud that it specifies immersion.
