Proverbs 19:11 The discretion of a man deferreth his anger; and it is his glory to pass over a transgression.
12 The king’s wrath is as the roaring of a lion; but his favour is as dew upon the grass.
This starts telling us that a man who is slow to anger is using the wisdom given him by God. He has developed to some degree patience and this helps him to overlook transgressions by others and not spreading the faults of these. It could also be said that he has forgive the person for the wrong they have done. This to is showing wisdom because God’s word says forgive and ye shall be forgiven. Next we see how a person with power is perceived by people. He is seen as someone with great power, even to control life and death, so people are some what afraid of him. But everyone desires to have the favor of the person of authority because he can decide whether they succeed or fail. Our prayer here would be to be like the person in the verse and pray that the person in the second verse operates with the wisdom of God so people will prosper under him.
