Job 28:2-4

Names of God Bible

²         Iron is taken from the ground,
            and rocks are melted for their copper.
³ Humans bring an end to darkness there
    and search to the limit of the gloomy, pitch-black rock.
⁴ They open up a mineshaft far from civilization,
    where no one has set foot.
    In this shaft men dangle and swing back and forth.
