Matthew 12:40

Overview - Matthew 12
1	Christ reproves the blindness of the Pharisees concerning the breach of the sabbath,
3	by scripture,
9	by reason,
13	and by a miracle.
22	He heals a man possessed that was blind and dumb;
24	and confuting the absurd charge of casting out devils by Beelzebub, he shows that blasphemy against the Holy Ghost shall never be forgiven.
36	Account shall be made of idle words.
38	He rebukes the unfaithful, who seek after a sign,
46	and shows who is his brother, sister, and mother.
