Ecclesiastes 1:17-18 And I gave my heart to know wisdom, and to know madness and folly: I perceived that this also is vexation of spirit. For in much wisdom is much grief: and he that increaseth knowledge increaseth sorrow.
Ecclesiastes 2:4,8,11 I made me great works; I builded me houses; I planted me vineyards: I gathered me also silver and gold, and the peculiar treasure of kings and of the provinces: I gat me men singers and women singers, and the delights of the sons of men, as musical instruments, and that of all sorts. Then I looked on all the works that my hands had wrought, and on the labour that I had laboured to do: and, behold, all was vanity and vexation of spirit, and there was no profit under the sun.
Psalm 107:9 For he satisfieth the longing soul, and filleth the hungry soul with goodness.
