Job 28:19-21 Young's Literal Translation (YLT)
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.
