Ecclesiastes 8:15
Then I commended mirth, because a man hath no better thing under the sun, than to eat, and to drink, and to be merry: for that shall abide with him of his labour the days of his life, which God giveth him under the sun.
Ecclesiastes 9:7
Go thy way, eat thy bread with joy, and drink thy wine with a merry heart; for God now accepteth thy works.
