Ecclesiastes 9:5

9:5 For the living know that they will die, but the dead do not know anything;

they have no further reward – and even the memory of them disappears.

Ecclesiastes 9:10

9:10 Whatever you find to do with your hands,

do it with all your might,

because there is neither work nor planning nor knowledge nor wisdom in the grave,

the place where you will eventually go.
