Matthew 5:17-19; Matthew 24:34-35

17 "Don't think that I have come to abolish the Torah or the Prophets. I have come not to abolish but to complete.

18 Yes indeed! I tell you that until heaven and earth pass away, not so much as a yud or a stroke will pass from the Torah -- not until everything that must happen has happened.

19 So whoever disobeys the least of these mitzvot and teaches others to do so will be called the least in the Kingdom of Heaven. But whoever obeys them and so teaches will be called great in the Kingdom of Heaven.

34 Yes! I tell you that this people will certainly not pass away before all these things happen.

35 Heaven and earth will pass away, but my words will never pass away.
