Job 10:21

¹⁹ I should have been as though I had not been; I should have been carried from the womb to the grave.

²⁰ Are not my days few? cease then, and let me alone, that I may take comfort a little,

Before I go whence I shall not return, even to the land of darkness and the shadow of death;

²² A land of darkness, as darkness itself; and of the shadow of death, without any order, and where the light is as darkness.

Do read the surrounding verses too, because the context often says more than a single verse.
