'Guide' in the Bible

I explored with my mind how to gratify myself with wine while [at the same time] having my mind remain steady and guide me wisely; and how to take control of foolishness, until I could see what was good for the sons of men to do under heaven all the days of their lives.

The words of the wise are pointed, and sayings grouped together are like nails fixed with a hammer; they are given by one guide.
