Matthew 5:19

Ὃς ἐὰν οὖν λύσῃ μίαν τῶν ἐντολῶν τούτων τῶν ἐλαχίστων καὶ διδάξῃ οὕτως τοὺς ἀνθρώπους ἐλάχιστος κληθήσεται ἐν τῇ βασιλείᾳ τῶν οὐρανῶν· ὃς δ’ ἂν ποιήσῃ καὶ διδάξῃ οὗτος μέγας κληθήσεται ἐν τῇ βασιλείᾳ τῶν οὐρανῶν.

Therefore, whoever shall break one of the least of these commandments, and shall teach men to do so, will be called the least in the Kingdom of Heaven, but whoever shall do and teach them will be called great in the Kingdom of Heaven.
