Wisdom 6:9

9 Unto you therefore, O kings, do I speak, that ye may learn wisdom, and not fall away.

Wisdom 6:9 In-Context

7 For he which is Lord over all shall fear no man's person, neither shall he stand in awe of any man's greatness: for he hath made the small and great, and careth for all alike.
8 But a sore trial shall come upon the mighty.
9 Unto you therefore, O kings, do I speak, that ye may learn wisdom, and not fall away.
10 For they that keep holiness holily shall be judged holy: and they that have learned such things shall find what to answer.
11 Wherefore set your affection upon my words; desire them, and ye shall be instructed.
