Ecclesiastes 3:12-13; Ecclesiastes 3:22
And I have known that there was no better thing than to rejoice, and to do well in this life.
For every man that eateth and drinketh, and seeth good of his labour, this is the gift of God.
And I have found that nothing is better than for a man to rejoice in his work, and that this is his portion. For who shall bring him to know the things that shall be after him?
