Even those who live many years should rejoice in them all; yet let them remember that the days of darkness will be many. All that comes is vanity.
Rejoice, young man, while you are young, and let your heart cheer you in the days of your youth. Follow the inclination of your heart and the desire of your eyes, but know that for all these things God will bring you into judgment.
