But I can explain the two sentences you mentioned.
Understanding of this sentence in the Old Testament: The law is good and everyone should obey it, so "those who violate the law praise the wicked"-because the wicked are just those who violate the law without suffering from the law. This is what collusion means.
The New Testament explains this sentence: Everyone is a sinner. In the era of salvation, people should not take revenge, but help and care for each other with sympathy and pity. In the eyes of God, the wicked and the unholy are sinners, they don't know God, they are spiritually ignorant, and there is not much difference. So "don't be an enemy of the wicked." If you continue reading the following, you will understand: "Matt. Only I told you to love your enemies and pray for those who persecute you. So that you can be the son of your heavenly father; Because he told the sun to shine on good people and bad people; Rain has given the just and the unjust. If you only love those who love you, what do you get in return? Even tax collectors can't do this? If you greet your brother alone, what advantages do you have over others? Not even foreigners? Therefore, you should be perfect, just like your heavenly father. "
