Jesus explains His view of the law very quickly after giving the beautitudes.(Matthew 5:17) Jesus, by explaining, expanding and exemplifying God's law,fulfilled a prophecy of the Messiah found in Isaiah 42:21: "The Lord is well pleased for His righteousness' sake; He will exalt the law, and make it honorable."The Hebrew word gadal, translated "exalt" or "magnify"(KJV) literally means "to be or become great".    Jesus Christ did exactly that, showing the holy, spiritual intent, purpose and scope of Gods law. He met the laws requirements by obeying it perfectly in thought and deed, both in the letter and in the intent of the heart.
