to carry it himself, R. Meir makes them both culpable, but R. Jehudah and R. Simeon declare them both innocent. If, of the two, neither was able (to do it himself), R. Jehudah and R. Meir declare them culpable and R. Simeon declares them free. If one of the two, however, was able, and the other unable, all agree that the able man is culpable." Whence is all this deduced? From what the rabbis taught: It is written [Lev. iv. 2]: "If any person sin," etc., i.e., if he committed the whole deed but not a part of it. How so? If two persons held one pitchfork and threw grain with it, or a weaver's spindle and wove with it, or a quill and wrote with it, or a reed and carried it into public ground, one might say that they are culpable. It is written [ibid.]: "If any person sin," etc. But if two persons held a date-press, or a log, and carried them out into public ground, R. Jehudah says, if one of the two was not able to carry it himself and they both carried it, they are both culpable, but if either of them was able, both are not culpable. R. Simeon says, even if one alone is not able to carry it and they carried it out together, they are also free. For only referring to such an instance the Scriptures say: "If any person," etc., and it is plain that one is culpable if he performs work alone, but if two persons did one thing they are both free.
The master said: If one of the two was able to perform the work alone and the other unable, all agree that he is culpable. Which of them was culpable? R. Hisda said, the one who was able. As to the one who was unable, why should he be so? What did he? Said R. Hamnuna to R. Hisda: "Why not? Did he not assist the one who was able? Answered R. Hisda: Assisting is not of consequence (because if he alone is not able to perform the work himself, his assistance is of no value). Said R. Zbid in the name of Rabha: "We have also learned in a Boraitha in support of this argument: If one suffering from a venereal disease rides an animal, the feet of which are encased in four pieces of cloth, the pieces of cloth are not subject to defilement, for the reason that the animal is able to stand on three feet." Why are they not subject to defilement? Was not one foot a help to the other three? Hence we must assume that one of the feet must be regarded as a help to the other three; a mere help, however, not having any legal consequence cannot become defiled, and as it is impossible to determine which one of the three feet is to be regarded as a help, all four pieces of cloth encasing them are not subject to defilement.
Again the master said: If either of the two were able, R.
