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

Titus 2:1

1 But speak thou the things which befit sound doctrine:

Titus 2:7-8

7 in all things showing thyself to be a pattern of good works; in doctrine showing uncorruptness, seriousness, sincerity,

8 sound speech which cannot be condemned, that he that is of a contrary mind may be ashamed, having no evil thing to say of you.

Titus 2:15

15 These things speak and exhort, and rebuke with all authority. Let no man despise thee.
