Titus 2:1; Titus 2:7-8; Titus 2:15

Titus 2:1

1 But you must teach what agrees with sound doctrine.

Titus 2:7-8

7 In all things you yourself must be an example of good behavior. Be sincere and serious in your teaching.

8 Use sound words that cannot be criticized, so that your enemies may be put to shame by not having anything bad to say about us.

Titus 2:15

15 Teach these things and use your full authority as you encourage and rebuke your hearers. Let none of them look down on you.
