For everything there is a season, and a time for every matter under heaven: 
a time to be born, and a time to die;
a time to plant, and a time to pluck up what is planted; 
a time to kill, and a time to heal;
a time to break down, and a time to build up; 
a time to weep, and a time to laugh;
a time to mourn, and a time to dance;

Ecclesiastes 3:1-4
