1. What the king should avoid (1-7)
We are a royal priesthood. As a godly king should avoid, so men should not spend their strength on women. We should not crave wine and beer. A drunkard drinks and forgets what the law decrees and deprives all the oppressed of their rights. Only perishing people who are in anguish like drinking.
2. What the king should do (8-9)
He must speak up for those who cannot speak for themselves, for the right of all who are destitute (2Sam 14:4-11). To love God is to love our neighbors.
