מכות א׳:ו׳ - א׳:ז׳

The conspiring witnesses are executed only if they are rendered conspiring witnesses after the verdict of the accused is concluded. This is in contrast to the opinion of the Sadducees, as the Sadducees say: Conspiring witnesses are executed only if they are rendered conspiring witnesses after the accused is killed on the basis of their testimony, as it is stated: “A life for a life” (Exodus 21:23; see Deuteronomy 19:21). The Rabbis said to the Sadducees: But wasn’t it already stated: “And you shall do to him as he conspired to do to his brother” (Deuteronomy 19:19), and this latter verse indicates that his accused brother is alive? And if so, why is it stated: “A life for a life”? One might have thought that if they are rendered conspiring witnesses from the moment the judges accepted their testimony in court, they will be executed, even though no verdict was concluded. Therefore, the verse states: “A life for a life,” teaching that they are executed only if they are rendered conspiring witnesses after the verdict of the accused will be concluded, from the moment that the court is on the verge of taking his life.

It is written: “At the mouth of two witnesses or three witnesses shall he who is to die be executed” (Deuteronomy 17:6). The question is: If the testimony is valid with two witnesses, why did the verse specify that it is valid with three? Rather, it is to juxtapose and liken three to two: Just as three witnesses can render the two witnesses conspiring witnesses, so too, the two witnesses can render the three wit-nesses conspiring witnesses. And from where is it derived that two witnesses can render even one hundred witnesses conspiring witnesses? It is derived from a verse, as the verse states: “Three witnesses.” Since the verse is obviously discussing witnesses, the term witnesses is superfluous, as it could have stated: Two or three. The term “witnesses” teaches that two witnesses can render a set of witnesses conspiring witnesses irrespective of their number. Rabbi Shimon says that three witnesses are mentioned in the verse in order to teach: Just as two witnesses who testified that a person is liable to be executed are not killed for this testimony unless both of them are found to be conspiring witnesses, so too, three witnesses who testified together are not killed unless all three of them are found to be conspiring witnesses. And from where is it derived that the same halakha applies even to one hundred witnesses? It is derived from a verse, as the verse states: “Three witnesses.” The superfluous term “witnesses” teaches that the status of all witnesses who come to court as a single set of witnesses is that of one testimony with regard to this halakha. Rabbi Akiva says: The third witness mentioned in this verse does not come for the judges to be lenient concerning him; rather, its mention comes for the judges to be stringent concerning him and to render his halakhic status like that of these two witnesses who testified with him. One could claim that since the testimony of the third witness is superfluous, as the testimony of the other two witnesses sufficed, the third witness and any other witnesses beyond the first two should be exempt. Therefore, the verse teaches that since he testified with them and was rendered a conspiring witness with them, he too is executed. One can learn a moral from this halakha: And if the verse punished one who associates with transgressors with a punishment like the one received by the transgressors, even though his role in the transgression is ancillary, all the more so will God pay a reward to one who associates with those who perform a mitzva like the reward of those who perform the mitzva themselves, even though his role in performing the mitzva is ancillary.
