'Labour' in the Bible

What advantage is to man by all his labour that he laboureth at under the sun?

And all that mine eyes asked I kept not back from them; I withheld not my heart from any joy, for my heart rejoiced because of all my labour, and this hath been my portion, from all my labour,

and I have looked on all my works that my hands have done, and on the labour that I have laboured to do, and lo, the whole is vanity and vexation of spirit, and there is no advantage under the sun!

And I have hated all my labour that I labour at under the sun, because I leave it to a man who is after me.

And who knoweth whether he is wise or foolish? yet he doth rule over all my labour that I have laboured at, and that I have done wisely under the sun! this also is vanity.

And I turned round to cause my heart to despair concerning all the labour that I laboured at under the sun.

For there is a man whose labour is in wisdom, and in knowledge, and in equity, and to a man who hath not laboured therein he giveth it -- his portion! Even this is vanity and a great evil.

For what hath been to a man by all his labour, and by the thought of his heart that he laboured at under the sun?

There is nothing good in a man who eateth, and hath drunk, and hath shewn his soul good in his labour. This also I have seen that it is from the hand of God.

yea, even every man who eateth and hath drunk and seen good by all his labour, it is a gift of God.

And I have seen all the labour, and all the benefit of the work, because for it a man is the envy of his neighbour. Even this is vanity and vexation of spirit.

Better is a handful with quietness, than two handfuls with labour and vexation of spirit.'

There is one, and there is not a second; even son or brother he hath not, and there is no end to all his labour! His eye also is not satisfied with riches, and he saith not, 'For whom am I labouring and bereaving my soul of good?' This also is vanity, it is a sad travail.

The two are better than the one, in that they have a good reward by their labour.

As he came out from the belly of his mother, naked he turneth back to go as he came, and he taketh not away anything of his labour, that doth go in his hand.

Lo, that which I have seen: It is good, because beautiful, to eat, and to drink, and to see good in all one's labour that he laboureth at under the sun, the number of the days of his life that God hath given to him, for it is his portion.

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.

All the labour of man is for his mouth, and yet the soul is not filled.

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.

then I considered all the work of God, that man is not able to find out the work that hath been done under the sun, because though man labour to seek, yet he doth not find; and even though the wise man speak of knowing he is not able to find.

See life with the wife whom thou hast loved, all the days of the life of thy vanity, that He hath given to thee under the sun, all the days of thy vanity, for it is thy portion in life, even of thy labour that thou art labouring at under the sun.

The labour of the foolish wearieth him, In that he hath not known to go unto the city.
