R. Yehudah says: His punishment is not delayed, but he is put to death immediately, and they write and send:" This and this man was put to death by beth-din."
And whence is it derived (that the same applies to) one who said "I will serve" (idolatry), "I will go and serve," "Let us go and serve"; "I will go and sacrifice," "Let us go and sacrifice"; I will go and offer incense," "Let us go and offer incense"; I will go and pour a libation," "Let us go and pour a libation"; "I will bow down," "I will go and bow down," "Let us go and bow down"? From "And they shall not do again according to this evil thing" — not according to the thing and not according to the evil.
