Restrain Anger...

A person’s wisdom yields patience;
    it is to one’s glory to overlook an offense. (NIV)

Good sense makes a man restrain his anger, and it is his glory to overlook a transgression or an offense. (Amplified)

The discretion of a man deferreth his anger; and it is his glory to pass over a transgression. (KJV)

~ Proverbs 19:11

Sound Wisdom and Discretion;

My son, do not let wisdom and understanding out of your sight, preserve sound judgment and discretion; 

~ Proverbs 3:21 (NIV)

Attention to Wisdom

My son, give attention to my wisdom,
Incline your ear to my understanding;
2 That you may observe discretion
And your lips may reserve knowledge.

~ Proverbs 5:1-2 (NASB)

To Attain Wisdom...

1 The proverbs of Solomon son of David, king of Israel:

2 for attaining wisdom and discipline;
for understanding words of insight;
3 for acquiring a disciplined and prudent life,
doing what is right and just and fair;
4 for giving prudence to the simple,
knowledge and discretion to the young—
5 let the wise listen and add to their learning,
and let the discerning get guidance—
6 for understanding proverbs and parables,
the sayings and riddles of the wise.

Proverbs 1:1-6 I(NIV 1984)

Moral Benefits of Wisdom

My son, if you accept my words and store up my commands within you, turning your ear to wisdom and applying your heart to understanding, and if you call out for insight and cry aloud for understanding, and if you look for it as for silver and search for it as for hidden treasure, then you will understand the fear of the LORD and find the knowledge of God. For the LORD gives wisdom, and from his mouth come knowledge and understanding. He holds victory in store for the upright, he is a shield to those whose walk is blameless, for he guards the course of the just and protects the way of his faithful ones. Then you will understand what is right and just and fair—every good path. For wisdom will enter your heart, and knowledge will be pleasant to your soul. Discretion will protect you, and understanding will guard you. Wisdom will save you from the ways of wicked men.
