There is a time for everything, and a season for every activity under heaven:  
a time to be born and a time to die, a time to plant and a time to uproot, a time to kill and a time to heal, a time to tear down and a time to build, a time to weep and a time to laugh, a time to mourn and a time to dance, a time to scatter stones and a time to gather them, a time to embrace and a time to refrain, a time to search and a time to give up, a time to keep and a time to throw away, a time to tear and a time to mend, a  time to be silent and a time to speak, a time to love and a time to hate, a time for war and a time for peace.
Ecclesiastes 3:1-8
