17Think not that I came to destroy the law or the prophets: I came not to destroy, but to fulfil. 18For verily I say unto you, Till heaven and earth pass away, one jot or one tittle shall in no wise pass away from the law, till all things be accomplished. 19Whosoever therefore shall break one of these least commandments, and shall teach men so, shall be called least in the kingdom of heaven: but whosoever shall do and teach them, he shall be called great in the kingdom of heaven.
Matthew 5:17-19 (ASV)
