What does the Bible say about righteousness and kings?

In Proverbs 16:13, it is stated that righteous lips are the delight of kings. This highlights that true authority, exemplified by the perfect King, desires righteousness and truth. Kings are meant to rule justly and make wise judgments based on accurate information. Just as an earthly king relies on truthful advisors for justice, the heavenly King, the Lord Jesus Christ, values those who communicate His truth, not because He needs the information, but because His subjects need to receive it. This principle underscores a fundamental truth about the nature of authority and righteousness in a spiritual context.
