Job 28:11 (KJV)

The stones of it are the place of sapphires: and it hath dust of gold.

There is a path which no fowl knoweth, and which the vulture's eye hath not seen:

The lion's whelps have not trodden it, nor the fierce lion passed by it.

He putteth forth his hand upon the rock; he overturneth the mountains by the roots.

He cutteth out rivers among the rocks; and his eye seeth every precious thing.

But where shall wisdom be found? and where is the place of understanding?

Man knoweth not the price thereof; neither is it found in the land of the living.

The depth saith, It is not in me: and the sea saith, It is not with me.

It cannot be gotten for gold, neither shall silver be weighed for the price thereof.

It cannot be valued with the gold of Ophir, with the precious onyx, or the sapphire.
