Fool

Matthew 5:22 But I say unto you, That whosoever is angry with his brother without a cause shall be in danger of the judgment: and whosoever shall say to his brother, Raca, shall be in danger of the council: but whosoever shall say, Thou fool, shall be in danger of hell fire.

The whole context of the statement is about anger with brethren and calling them fool which is the word moros. Bit there are many fools that are not brethren and Christ says so.
