(Ibid. 15) "One witness shall not arise against a man": This tells me only of capital offenses. Whence do I derive (the same for) the administration of stripes? From "for every transgression."
Whence do I derive (the same for cases involving) sacrifices? From "for every sin (-offering)."
Whence do I derive (the same for) confirming one as a Cohein or disqualifying him from the priesthood? From "in every fault."
Whence do I derive (the same for) monetary litigations? From "wherein he is amiss."
This tells me only of testimony concerning a man. Whence do I derive (the same for) testimony concerning women and slaves? From "in every" "and in every." If in the end we include a woman, why is it written "a man"? He (a single witness) does arise for a woman (to testify that her husband has died) to (enable her) to wed (another). These are the words of R. Yehoshua.
