¹³ And 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.

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

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

¹⁶ I communed with mine own heart, saying, Lo, I am come to great estate, and have gotten more wisdom than all they that have been before me in Jerusalem: yea, my heart had great experience of wisdom and knowledge.

¹⁷ And I gave my heart to know wisdom, and to know madness and folly: I perceived that this also is vexation of spirit.

¹⁸ For in much wisdom is much grief: and he that increaseth knowledge increaseth sorrow.

¹³ Then I saw that wisdom excelleth folly, as far as light excelleth darkness.

¹⁴ The wise man's eyes are in his head; but the fool walketh in darkness: and I myself perceived also that one event happeneth to them all.

¹⁵ Then said I in my heart, As it happeneth to the fool, so it happeneth even to me; and why was I then more wise? Then I said in my heart, that this also is vanity.

³ As I besought thee to abide still at Ephesus, when I went into Macedonia, that thou mightest charge some that they teach no other doctrine,

⁴ Neither give heed to fables and endless genealogies, which minister questions, rather than godly edifying which is in faith: so do.

⁹ But avoid foolish questions, and genealogies, and contentions, and strivings about the law; for they are unprofitable and vain.
