It wasn't Jesus' intention to give the people
the idea that He was coming to overthrow
the Law.

He said, "Think not that I am come to destroy,..
but to fulfill the Law." Matthew 5:17

The law said:
"You have heard that it was said to the people
long ago, 'Do not murder, and anyone who
murders will be subject to judgment.'
But I tell you that anyone who is angry with his
brother will be subject to judgment. Again,
anyone who says to his brother, 'Raca, ' is
answerable to the Sanhedrin. But anyone who
says, 'You fool!' will be in danger of the fire of
hell.....
"You have heard that it was said, 'Do not
commit adultery.' But I tell you that anyone
who looks at a woman lustfully has already
committed adultery with her in his heart."
Matthew 5:21-22 27-28

But Jesus took them above the old law by
telling them to "Love your enemies, bless
them that curse you, do good to them that
hate you, and pray for them which despite-
fully use you, and persecute you...."
Matthew 5:44 With love no one would
commit the acts against the law thus they
would fulfill it.
