When you make a promise to God, don't fail to keep it, since he isn't pleased with fools. Keep what you promise

Always keep your garments white, and don't fail to anoint your head.

So enjoy yourself in your youth, young man, and be encouraged during your younger days. Live as you like, consistent with your world view, but keep in mind that God will bring you to account for everything.
