Ecclesiastes 5
6 Suffer not thy mouth to sin; neither say thou before the angel, that it was an error: wherefore should God be angry at thy voice, and destroy the work of thine hands?
7 For in the multitude of dreams and many words there are also divers vanities: but fear thou God.
Ecclesiastes 7
1 A good name is better than precious ointment, and the day of death than the day of one's birth.
23 All this have I proved by wisdom: I said, I will be wise; but it was far from me.
24 That which is far off, and exceeding deep, who can find it out?
25 I applied mine heart to know, and to search, and to seek out wisdom, and the reason of things, and to know the wickedness of folly, even of foolishness and madness:
26 And I find more bitter than death the woman, whose heart is snares and nets, and her hands as bands: whoso pleaseth God shall escape her; but the sinner shall be taken by her.
27 Behold, this have I found, saith the preacher, counting one by one, to find out the account:
28 Which yet my soul seeketh, but I find not: one man among a thousand have I found; but a woman among all those have I not found.
29 Lo, this only have I found, that God hath made man upright; but they have sought out many inventions.
Ecclesiastes 8
1 Who is as the wise man? and who knoweth the interpretation of a thing? a man's wisdom maketh his face to shine, and the boldness of his face shall be changed.
16 When I applied mine heart to know wisdom, and to see the business that is done upon the earth: (for also there is that neither day nor night seeth sleep with his eyes:)
17 Then I beheld all the work of God, that a man cannot find out the work that is done under the sun: because though a man labour to seek it out, yet he shall not find it; yea further, though a wise man think to know it, yet shall he not be able to find it.
