Chapter 9:7
Go thy way, eat thy bread with joy, and drink thy wine with a merry heart; for God now accepteth thy works.
Chapter 9:10-11
Whatsoever thy hand findeth to do, do it with thy might. I returned, and saw under the sun, that the race is not to the swift, nor the battle to the strong, neither yet bread to the wise, nor yet riches to men of understanding, nor yet favour to men of skill; but time and chance happeneth to them all.
