Ecclesiastes 1:12

1:11 There is no remembrance of former things, Nor will there be any remembrance of things that are to come By those who will come after.

1:12 I, the Preacher, was king over Israel in Jerusalem.

1:13 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.
