▼ The “wickedness” mentioned here (רֶשַׁע, resha’) might better be understood as a criminal act, for the related word “wicked” can also mean the guilty criminal. If a king is trying to have a righteous administration, he will detest any criminal acts.

▼ The “throne” represents the administration, or the decisions made from the throne by the king, and so the word is a metonymy of adjunct (cf. NLT “his rule”).
