"But speak thou the things which become sound doctrine:"
–verb (used with object)
|3.||to be attractive on; befit in appearance; look well on: That gown becomes you.|
|4.||to be suitable or necessary to the dignity, situation, or responsibility of: conduct that becomes an officer.|
From the verse and the meaning of the word, I understand that Titus 2 is a discussion of things that are "suitable or necessary to the dignity" of sound doctrine.
I want to be suitable, so I think the chapter deserves my attention.
