Matthew 5:19

19Whoeverὃςifἐὰνthenοὖνshall breakλύσῃoneμίανof theτῶνcommandmentsἐντολῶνof theseτούτωνtheτῶνleastἐλαχίστωνandκαὶshall teachδιδάξῃsoοὕτωςtheτοὺςothersἀνθρώπους,leastἐλάχιστοςhe will be calledκληθήσεταιinἐνtheτῇkingdomβασιλείᾳof theτῶνheavensοὐρανῶν·whoeverὃςnowδ’ἂνshall keepποιήσῃandκαὶshall teach [them]διδάξῃ,this [one]οὗτοςgreatμέγαςwill be calledκληθήσεταιinἐνtheτῇkingdomβασιλείᾳof theτῶνheavensοὐρανῶν.

Whoever then may break one of the least of these commandments and may teach men thus, he will be called least in the kingdom of the heavens; but whoever may do and may teach [them], this one will be called great in the kingdom of the heavens.
