'Rejoice' in the Bible

So I realized that there is {nothing better} for them than to {rejoice and enjoy themselves} during their lives.

There is no end to all the people, to all who were before him. Yet the later generation will not rejoice in him, for this also [is] vanity and chasing wind!

This indeed is a gift of God: everyone to whom God gives wealth and possessions, he also empowers him {to enjoy them}, to accept his lot, and to rejoice in [the fruit of] his toil.

In the day of prosperity, rejoice! But in the day of adversity, consider! For God made one in place of another so that mortals cannot find out what will happen {in the future}.

So I recommend enjoyment. For there [is] nothing better for man under the sun than to eat and to drink and to rejoice. This will accompany him in his toil the days of his life that God gives to him under the sun.

For if a man lives many years, let him rejoice in all of them! Let him remember that the days of the darkness will be many-- all that is coming [is] vanity!

Rejoice, O young man, in your youth, and let your heart cheer you in the days of your youth! Follow the ways of your heart and the sight of your eyes-- but know that God will bring you into judgment for all these things.
