Ecclesiastes 2:3; Ecclesiastes 5:6; Ecclesiastes 11:10

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.

6 Suffer not thy mouth to cause thy flesh to sin; neither say thou before the angel, that it was an error: wherefore should God be angry at thy voice, and destroy the work of thine hands?

10 Therefore remove sorrow from thy heart, and put away evil from thy flesh: for childhood and youth are vanity.
