NET

3 I thought deeply about the effects of indulging myself with wine (all the while my mind was guiding me with wisdom) and the effects of behaving foolishly, so that I might discover what is profitable for people to do on earth during the few days of their lives.

Darby

3 I searched in my heart how to cherish my flesh with wine, while practising my heart with wisdom; and how to lay hold on folly, till I should see what was that good for the children of men which they should do under the heavens all the days of their life.

KJV

3 I sought in mine heart to give myself unto wine, yet acquainting mine heart with wisdom; and to lay hold on folly, till I might see what [was] that good for the sons of men, which they should do under the heaven all the days of their life.
