The bible says this.
Ecclesiastes 3:1-2, 4-8
For everything there is a season, and a time for every purpose under heaven: A time to be born, and a time to die; a time to plant, and a time to pluck up that which is planted; a time to weep, and a time to laugh; a time to mourn, and a time to dance; a time to cast away stones, and a time to gather stones together; a time to embrace, and a time to refrain from embracing; a time to seek, and a time to lose; a time to keep, and a time to cast away; a time to rend, and a time to sew; a time to keep silence, and a time to speak; a time to love, and a time to hate; a time for war, and a time for peace.
