Titus 2:1-8

Duties of the Older and Younger

But as for you, speak the things which are fitting for sound doctrine.
2 Older men are to be temperate, dignified, sensible, sound in faith, in love, in perseverance. 3 Older women likewise are to be reverent in their behavior, not malicious gossips nor enslaved to much wine, teaching what is good, 4 so that they may encourage the young women to love their husbands, to love their children, 5 to be sensible, pure, workers at home, kind, being subject to their own husbands, so that the word of God will not be dishonored. 6 Likewise urge the young men to be sensible; 7 in all things show yourself to be an example of good deeds, with purity in doctrine, dignified, 8 sound in speech which is beyond reproach, so that the opponent will be put to shame, having nothing bad to say about us.

2 Timothy 2:2

2 The things which you have heard from me in the presence of many witnesses, entrust these to faithful men who will be able to teach others also.

Psalm 119:9

How can a young man keep his way pure?
By keeping it according to Your word.
