13 And I set my heart to seek and explore wisdom+ in relation to everything that has been done under the heavens—the calamitous occupation that God has given to the sons of mankind* in which to be occupied.+

3 I explored with my heart by cheering my flesh even with wine,+ while I was leading my heart with wisdom,+ even to lay hold on folly until I could see what good there was to the sons of mankind in what they did under the heavens for the number of the days of their life.+
