"Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them." (NIV)

Do not think that I have come to do away with or undo the Law or the Prophets; I have come not to do away with or undo but to complete and fulfill them. (AMP)

Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil. (KJV)
