Ecclesiastes 1:11-13

Young's Literal Translation

¹¹ There is not a remembrance of former [generations]; and also of the latter that are, there is no remembrance of them with those that are at the last.

¹² I, a preacher, have been king over Israel in Jerusalem.

¹³ And I have given my heart to seek and to search out by wisdom concerning all that hath been done under the heavens. It [is] a sad travail God hath given to the sons of man to be humbled by it.
