Job 28:3-5

Revised Standard Version Catholic Edition

³ Men put an end to darkness,
    and search out to the farthest bound
    the ore in gloom and deep darkness.
⁴ They open shafts in a valley away from where men live;
    they are forgotten by travelers,
    they hang afar from men, they swing to and fro.
⁵ As for the earth, out of it comes bread;
    but underneath it is turned up as by fire.
