פּירוש אויף ויקרא 24:16

ונקב שם AND HE THAT UTTERETH BLASPHEMOUSLY THE NAME [OF THE LORD SHALL SURELY BE PUT TO DEATH] — He is not liable to the death-penalty at the hand of the judges unless he utters the Divine Tetragrammaton blasphemously, but not if he execrateth the Lord by only mention of one of the substitutes for the Divine name (e. g., רחום, חנון, אל etc.), (cf. Sifra, Emor, Chapter 19 5; Sanhedrin 56a).

ונוקב שם ה' מות יומת, the penalty of someone cursing the tetragram is not comparable to the punishment for someone who “merely” cursed one of G’d’s attributes. The individual described in our verse will be executed publicly by stoning, and all who heard him commit this crime must participate actively in the execution.

HE SHALL BE PUT TO DEATH. This is to be explained in this manner, according to its plain sense.

ונקב here is an expression denoting “cursing”, like (Numbers 23:8) “How shall I curse (אקב) [when God hath not cursed]” (Sanhedrin 56a).
