'Good Teacher' in the Bible

And lo, one having come near, said to him, 'Good teacher, what good thing shall I do, that I may have life age-during?'

And as he is going forth into the way, one having run and having kneeled to him, was questioning him, 'Good teacher, what may I do, that life age-during I may inherit?'

And a certain ruler questioned him, saying, 'Good teacher, what having done -- shall I inherit life age-during?'
