[13] Consider the work of God:

who can make straight what he has made crooked?

[14] In the day of prosperity be joyful, and in the day of adversity consider: God has made the one as well as the other, so that man may not find out anything that will be after him.

[15] In my vain life I have seen everything. There is a righteous man who perishes in his righteousness, and there is a wicked man who prolongs his life in his evildoing. [16] Be not overly righteous, and do not make yourself too wise. Why should you destroy yourself? [17] Be not overly wicked, neither be a fool. Why should you die before your time? [18] It is good that you should take hold of this, and from that withhold not your hand, for the one who fears God shall come out from both of them.

[19] Wisdom gives strength to the wise man more than ten rulers who are in a city.

[20] Surely there is not a righteous man on earth who does good and never sins. (ESV)
