It couldn't be clearer in Proverbs 8:13.
The fear of the LORD is hatred of evil. Pride and arrogance and the way of evil and perverted speech I hate.
Matthew Henry explains from his Whole Commentary on the Bible, opens with saying that hating what God hates gives men good hearts. Then,
v. 13. True religion, consisting in the fear of the Lord, which is the wisdom before recommended, teaches men,
1. To hate all sin, as displeasing to God and destructive to the soul: The fear of the Lord is to hate evil, the evil way, to hate sin as sin, and therefore to hate every false way. Wherever there is an awe of God there is a dread of sin, as an evil, as only evil.
2. Particularly to hate pride and passion, those two common and dangerous sins. Conceitedness of ourselves, pride and arrogancy, are sins which Christ hates, and so do all those who have the Spirit of Christ; every one hates them in others, but we must hate them in ourselves,
The froward mouth*, peevishness towards others, God hates, because it is such an enemy to the peace of mankind, and therefore we should hate it. Be it spoken to the honor of religion that, however it is unjustly accused, it is so far from making men conceited and sour that there is nothing more directly contrary to it than pride and passion, nor which it teaches us more to detest.
*The froward mouth speaks false doctrines, and bad counsels and deceits.
*The froward mouth is the mouth that speaks perverse things
As the Geneva Study Bible says succinctly, "So that he who does not hate evil, does not fear God."
Kind of puts it into perspective, doesn't it?
Hate evil. This is wisdom.
