Ecclesiastes 1:13-15

¹³And I gave my heart to seek and search out by wisdom concerning all things that are done under heaven: this sore travail hath God given to the sons of man to be exercised therewith.

¹⁴I have seen all the works that are done under the sun; and, behold, all is vanity and vexation of spirit.

¹⁵That which is crooked cannot be made straight: and that which is wanting cannot be numbered.
