Ecclesiastes 9

5 For the living know that they shall die: but the dead know not any thing, neither have they any more a reward; for the memory of them is forgotten.

6 Also their love, and their hatred, and their envy, is now perished; neither have they any more a portion for ever in any thing that is done under the sun.

10 Whatsoever thy hand findeth to do, do it with thy might; for there is no work, nor device, nor knowledge, nor wisdom, in the grave, whither thou goest.

14 There was a little city, and few men within it; and there came a great king against it, and besieged it, and built great bulwarks against it:

15 Now there was found in it a poor wise man, and he by his wisdom delivered the city; yet no man remembered that same poor man.
