Ecclesiastes 4:8
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 5:13
There is a sore evil which I have seen under the sun, namely, riches kept for the owners thereof to their hurt.
Ecclesiastes 5:16
And this also is a sore evil, that in all points as he came, so shall he go: and what profit hath he that hath laboured for the wind?
