"Ye have heard that it was said by them of old time, Thou shalt not kill, and whosoever shall kill shall be in danger of the judgment, but I say unto you, That whosoever is angry with his brother without cause [the Revised Version leaves out "without cause"] shall be in danger of the judgment, and whosoever shall say to his brother, Vain fellow, shall be in danger of the council, but whosoever shall say, Thou fool, shall be in danger of hell fire.
A man who goes so far as to think of another that he is a fool and decides the question that he is a fool and then passes the sentence in words, "Thou fool," has committed murder, and the only thing that waits for him is hell fire.

Q: But what is the Savior talking about?
A: He is teaching them what it means when it says, "Thou shalt not kill." And when God said, "Thou shalt not kill," He forbade the thinking of a thought or the speaking of a word which if carried out to its utmost possible limit, could lead to killing or to doing harm."
