Ecclesiastes 1:13-17

Thomson(i) 13 and I applied my heart to seek and make diligent search by wisdom concerning all the things which are done on the earth. Because God hath assigned to the sons of men painful employment, that they may be kept employed, 14 I took a view of all the different sorts of work which are done under the sun. And behold they are all vanity and vexation of spirit. 15 That which is crooked cannot be made straight, nor can wants be numbered. 16 I communed with my heart, saying, Behold I am become great and have made advances in wisdom above all who were before me in Jerusalem. And I have applied my mind to know wisdom and knowledge. 17 And my mind hath taken a view of many things; of wisdom and knowledge; of parables and science. I have found by experience that this also is indeed vexation of spirit.
