2For in his own eyes he flatters himself too much to detect or hate his sin. The Psalmist is teaching that if we do not have the oracles in our hearts then we are practicing a form of flattery. The phrase in his own eyes is referring to his heart in the former verse.The Psalmist has the oracles in his heart be the wicked do not and that is flattery. The Psalmist is teaching that it is actually a heart filled with hate. That is when we accuse God of hate by cursing sin we cannot be justified because of the hate filled heart.

The words of his mouth are wicked and deceitful;
he has ceased to be wise and to do good.
Even on his bed he plots evil;
he commits himself to a sinful course
and does not reject what is wrong. He is comparing the words of the oracles to the words used by the wicked man. He uses the ideas and the words to create his own god. In other words since the man has not fear of God being that he hates the oracles then he practices making his own god or hating his neighbor. Its not even talking about the attitude of hate but the process by which he sees the reality. Think about all the christian who fail to judge correctly because of the laziness of knowing  the oracles. The grace that God gives is beyond our understanding. The judgements that we use are very self deceptive. But thank God we do not practice this sin the Psalmist speaks here. 4Even on his bed he plots evil; he commits himself to a sinful course and does not reject what is wrong.Unlike the christian the wicked man goes a step further and breaks up all  that is good in society. The sin is ra a. He does not reject ra a. The difference is that we are saved by grace and implanted with the word of God by grace. But the wicked have no understanding of God because they are not given the new man. So we practice the sin of rebellion...not judging by the oracles and the sin of making other gods, not knowing God by the oracles, but we do it out of a lack of understanding and not hate.

You can see that the Psalmist does not put the believer up against the wicked mans thoughts and actions. But He goes to describing the oracles of God. Any man who loves the oracles knows that God cannot accept our good works.This is Gods salvation in which defending God is defending Gods people.We speak the law, covenants, curses etc. Here the Psalmist is speaking the covenants love of God who has sworn upon Himself to carry it out. His unfailing love reaches to the heavens. If it was not for Gods love and faithfulness we too would break up all that is good in this world. But for the grace of God.  6 Your righteousness is like the mighty mountains, your justice like the great deep. The Psalmist uses the name EL the God who is sovereign and controls all things. This God never changes His law. He judges all things. His curses are always just. The only hate the Psalmist describes is the wicked who practice ra a and the righteous indignation of God in the curse. It is not our job to take vengeance.  7How priceless is your unfailing love! Both high and low among men
find refuge in the shadow of your wings.Gods righteous indignation is not hateful because He shows mercy allowing the wicked time to repent. His purpose is to save mankind. God is a good God all the time. He is speaking of Gods promises in the oracles. God promises to be the refuge that we can flee from all the dangers of  this world.
