Job 28:13

Man does not know its worth,

and it is not found in the land of the living.

No mortal comprehends its worth;

it cannot be found in the land of the living.

No one can know its value,

since it cannot be found in the land of the living.

No one knows where to find it,

for it is not found among the living.

Man knoweth not the price thereof;

Neither is it found in the land of the living.
