Job 28:21

21 It hath been hid from the eyes of all living. And from the fowl of the heavens It hath been hidden.

Job 28:21 In-Context

19 Not equal it doth the topaz of Cush, With pure gold it is not valued.
20 And the wisdom -- whence doth it come? And where [is] this, the place of understanding?
21 It hath been hid from the eyes of all living. And from the fowl of the heavens It hath been hidden.
22 Destruction and death have said: `With our ears we have heard its fame.'
23 God hath understood its way, And He hath known its place.
