Job 28:5-7

Amplified Bible

⁵ 
“[As for] the earth, out of it comes food,
But underneath [its surface, down deep] it is turned over as fire.
⁶ 
“Its stones are the bed of sapphires;
It holds dust of gold.
⁷ 
“The path [deep within] no bird of prey knows,
And the falcon’s eye has not caught sight of it.
