'Rejoice' in the Bible

I have known that there is no good for them except to rejoice and to do good during their life,

And I have seen that there is nothing better than that man rejoice in his works, for it is his portion; for who doth bring him in to look on that which is after him?

there is no end to all the people, to all who were before them; also, the latter rejoice not in him. Surely this also is vanity and vexation of spirit.

Every man also to whom God hath given wealth and riches, and hath given him power to eat of it, and to accept his portion, and to rejoice in his labour, this is a gift of God.

And I have praised mirth because there is no good to man under the sun except to eat and to drink, and to rejoice, and it remaineth with him of his labour the days of his life that God hath given to him under the sun.

But, if man liveth many years, In all of them let him rejoice, And remember the days of darkness, For they are many! all that is coming is vanity.

Rejoice, O young man, in thy childhood, And let thy heart gladden thee in days of thy youth, And walk in the ways of thy heart, And in the sight of thine eyes, And know thou that for all these, Doth God bring thee into judgment.
