Job 28:7 in the World English Bible
That path no bird of prey knows, neither has the falcon’s eye seen it.
Context
6 The stones of it are the place of sapphires: and it hath dust of gold.
7 There is a path which no fowl knoweth, and which the vulture’s eye hath not seen:
8 The lion’s whelps have not trodden it, nor the fierce lion passed by it.
