Ecclesiastes 2:1-3

I said to myself, “Come now, I will test you with pleasure and gratification; so enjoy yourself and have a good time.” But behold, this too was vanity (futility, meaninglessness). [Luke 12:19, 20] I said of laughter, “It is madness,” and of pleasure, “What does it accomplish?” 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.
