You know the expression, “once a liar, always a liar.” It warns us not to trust someone who has knowingly been shown to be untrustworthy. On today’s daf, two rabbis, who agree that you can’t trust liars, and say you cannot trust their testimonies in the future, debate whether that means we can’t trust anything they have said up to this point in their testimony (including things they said before the lie) or that we can’t trust them from now on (after the lie).
GEMARA: One who is rendered a conspiring witness is barred from providing testimony in the future. The Gemara cites a fundamental dispute with regard to this disqualification. It was stated concerning a conspiring witness: Abaye says: He is disqualified retroactively, from when he provided his testimony. Any testimony he may have provided after that point in time is retroactively nullified. Rava says: He is disqualified only from that point forward, i.e., from when he was established to be a conspiring witness, but not retroactively from when he provided his testimony.
The Gemara explains the reasons for the two opinions: Abaye says he is disqualified retroactively because it is from that time when he testified that he is considered a wicked man, and the Torah said: “Do not put your hand with the wicked to be an unrighteous witness” (Exodus 23:1), which is interpreted to mean: Do not allow a wicked man to serve as a witness.
Rava says that he is disqualified only from that point forward because the disqualification of a conspiring witness is a novelty, i.e., it is not based on logic.
What a warning not to lie – not even when a friend convinces you (conspires with you). You have ruined your reputation and are no longer trust worthy. Interesting how it feels there is no going back. Here, we also are reminded that, if you lied as a witness so that a person would have to pay a fine, then you are liable to have to pay whatever they would have needed to pay.
It just makes me thing of all the corruption and injustice and wonder why we seem to put up with it. . .
