Ecclesiastes 1:8

8 All things are full of labour; man cannot utter it: the eye is not satisfied with seeing, nor the ear filled with hearing.

Ecclesiastes 4:8

8 There is one alone, and there is not a second; yea, he hath neither child nor brother: yet is there no end of all his labour; neither is his eye satisfied with riches; neither saith he, For whom do I labour, and bereave my soul of good? This is also vanity, yea, it is a sore travail.

Ecclesiastes 5:10

10 He that loveth silver shall not be satisfied with silver; nor he that loveth abundance with increase: this is also vanity.

Ecclesiastes 6:3

3 If a man beget an hundred children, and live many years, so that the days of his years be many, and his soul be not filled with good, and also that he have no burial; I say, that an untimely birth is better than he.
