daf bit: Ketubot 23
Feb. 26th, 2015 08:44 amThe last several pages have been talking about testimony and who is believed under what circumstances. Today's daf presents two cases. First, if two women were taken captive and later each one says "I am (ritually) pure", they are not believed. However, if one says of the other "she is pure", she is believed in the absence of other witnesses. But if one says "I am impure" she is believed. Claims about one's own purity are rejected; claims about one's impurity are accepted; claims of another's purity are accepted; and claims of another's impurity are rejected. In other words, you can say something beneficial about another or limiting about yourself and be believed, but not the reverse.
Lest we think this is just about women, the next mishna concerns two men who claim to be kohanim (priests) but have no other witnesses. Again, a man saying "I am a kohein" is not believed, but one saying that another is a kohein is believed. The g'mara then enters into a discussion about different levels of priesthood -- maybe we believe one's claim for the purposes of some functions but not for others. That is beyond the scope of this daf bit. (23b)
