'Labouring' in the Bible

There is one alone and without a second; also he hath neither son nor brother: yet is there no end of all his labour, neither is his eye satisfied with riches, and he saith not, For whom then am I labouring, and depriving my soul of good? This also is vanity and a grievous occupation.

Enjoy life with the wife whom thou lovest all the days of the life of thy vanity, which he hath given thee under the sun, all the days of thy vanity; for that is thy portion in life, and in thy labour wherein thou art labouring under the sun.
