μηδείς σου τῆς νεότητος καταφρονείτω, ἀλλὰ τύπος γίνου τῶν πιστῶν ἐν λόγῳ, ἐν ἀναστροφῇ, ἐν ἀγάπῃ, ἐν πνεύματι, ἐν πίστει, ἐν ἁγνείᾳ.
KJVLet no man despise thy youth; but be thou an example of the believers, in word, in conversation, in charity, in spirit, in faith, in purity.
Don't let anyone look down on you because you are young, but set an example for the believers in speech, in conduct, in love, in faith and in purity.
