'Cheerful' in the Bible

A glad heart maketh a cheerful countenance; But by sorrow of heart the spirit is broken.

All the days of the afflicted are evil; But he that is of a cheerful heart hath a continual feast.

A cheerful heart is a good medicine; But a broken spirit drieth up the bones.

Thus saith Jehovah of hosts: The fast of the fourth month , and the fast of the fifth, and the fast of the seventh, and the fast of the tenth, shall be to the house of Judah joy and gladness, and cheerful feasts; therefore love truth and peace.
