'Days of Your Youth' in the Bible

Rejoice, young man, while you are young, and let your heart cheer you in the days of your youth. Follow the impulses of your heart and the desires of your eyes, but know that God will judge your motives and actions.

So remember your Creator in the days of your youth -- before the difficult days come, and the years draw near when you will say, "I have no pleasure in them";

And with all your abominable practices and prostitution you did not remember the days of your youth when you were naked and bare, kicking around in your blood.

"'Because you did not remember the days of your youth and have enraged me with all these deeds, I hereby repay you for what you have done, declares the sovereign Lord. Have you not engaged in prostitution on top of all your other abominable practices?

Yet I will remember the covenant I made with you in the days of your youth, and I will establish a lasting covenant with you.
