'Course' in the Bible

The wind goeth toward the south, and turneth about unto the north; it turneth about continually in its course, and the wind returneth again to its circuits.

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.

I have seen personally what is the only beneficial and appropriate course of action for people: to eat and drink, and find enjoyment in all their hard work on earth during the few days of their life which God has given them, for this is their reward.
