Ecclesiastes 1:2; Ecclesiastes 1:12-14; Ecclesiastes 1:18

2 "Vanity of vanities," says the Preacher; "Vanity of vanities, all is vanity."

12 I, the Preacher, was king over Israel in Jerusalem.

13 And I set my heart to seek and search out by wisdom concerning all that is done under heaven; this burdensome task God has given to the sons of man, by which they may be exercised.

14 I have seen all the works that are done under the sun; and indeed, all is vanity and grasping for the wind.

18 For in much wisdom is much grief, And he who increases knowledge increases sorrow.
