Lamentations 3:27

Remember now thy Creator in the days of thy youth, while the evil days come not, nor the years draw nigh, when thou shalt say, I have no pleasure in them;

It is good for me that I have been afflicted; that I might learn thy statutes.

Blessed is the man whom thou chastenest, O LORD, and teachest him out of thy law;

So teach us to number our days, that we may apply our hearts unto wisdom.
