KJV - Again, I considered all travail, and every right work, that for this a man is envied of his neighbour. This is also vanity and vexation of spirit.
ASV - Then I saw all labor and every skilful work, that for this a man is envied of his neighbor. This also is vanity and a striving after wind.
BBE - And I saw that the cause of all the work and of everything which is done well was man's envy of his neighbour. This again is to no purpose and a desire for wind.
WEB - Then I saw all the labor and achievement that is the envy of a man's neighbor. This also is vanity and a striving after wind.
YLT - 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.
