For kings

Proverbs 16 is written to kings. Christians are prophets, priests, and kings. What is written to a king in Scripture is written to Christians.

Higher influences

A Christian needs to be educated by higher influences. Not just educated but built up. Higher influences in the categories of history, philosophy, science, religion, art, music, and imaginative literature. The higher influences in these categories will be more rare and harder to engage in terms of holding one's attention. The higher the influence, that is.
