7 Truly the light is sweet, and a pleasant thing it is for the eyes to behold the sun:
8 But if a man lives many years, and rejoices in them all; yet let him remember the days of darkness; for they shall be many. All that comes is vanity.
9 Rejoice, O young man, in your youth; and let your heart cheer you in the days of your youth, and walk in the ways of your heart, and in the sight of your eyes: but know that for all these things God will bring you into judgment.
10 Therefore remove sorrow from your heart, and put away evil from your flesh: for childhood and youth are vanity.
