Ecclesiastes 4:4-6

4 ¶ Again, I considered all travail, and every right work, that for this a man is envied of his neighbour. This is also vanity and vexation of spirit. 5 The fool foldeth his hands together, and eateth his own flesh. 6 Better is an handful with quietness, than both the hands full with travail and vexation of spirit.
