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

Titus 2:1

1 But speak thou the things which are expedient unto sound doctrine,

Titus 2:7-8

7 in all things showing thyself as an example of good works, in doctrine showing integrity, seriousness, purity,

8 sound speech, that cannot be condemned; that the adversary 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 one despise thee.
