Job 28:19-21

Young's Literal Translation

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.
