Ecclesiastes 3:6

A time to get, and a time to lose; a time to keep, and a time to cast away;

Gaining and losing each belong to their own appointed season, and neither is right for every moment. Keeping likewise has its proper time, just as casting away has its proper time. This order extends to all of life, so that even good activities like singing must be kept in their place. No singing or other activity should be allowed to crowd out or hinder important duties.
