Вайикра 24:14 Комментарий: Rashi, Ibn Ezra, Chizkuni & Siftei Chakhamim

השמעים THEY THAT HEARD — This refers to the witnesses.

all the witnesses will lay their hands… because someone may be stoned only by the testimony of witnesses.

וסמכו, “and all who heard the curse are to place their hands, etc.;” what was the reason for this procedure which had to be performed on the bodies of all people about to be executed legally? The reason is that when judgment was passed, the witnesses on whose testimony this sentence was based had been forced during the proceedings to literally quote the words used by the blasphemer in doing so. This had made them perform this symbolic act by means of which they transferred any guilt that they had been burdened with through that to the blasphemer before the latter was executed. כל השומעים, “all who had heard it;” seeing that he would be executed by stoning due to their testimony.

כל ALL [THOSE THAT HEARD] — 'all' serves to include the judges also (Sifra, Emor, Chapter 19 1).

את ידיהם [AND ALL THAT HEARD HIM SHALL LAY] THEIR HANDS [UPON HIS HEAD] — They said to him: your blood is upon your head; we do not deserve punishment on account of your death, for it was you yourself who brought it about (Sifra, Emor, Chapter 19 2).
