Matthew 5:18-19

For I assure you and most solemnly say to you, until heaven and earth pass away, not the smallest letter or stroke [of the pen] will pass from the Law until all things [which it foreshadows] are accomplished. So whoever breaks one of the least [important]of these commandments, and teaches others to do the same, will be called least [important] in the kingdom of heaven; but whoever practices and teaches them, he will be called great in the kingdom of heaven.
