The book of Job was the second Holy scripture given to humanity, after the book of Enoch, and before the Law of Moses. Job was son of Esaw brother of Jacob, and he is the only writing prophet of Old that didn’t come from Jacob/Israel (without counting Enoch, of course).
In chapter 28 he prophetically speaks of the “Original Place of Wisdom”:
“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. The gold and the crystal cannot equal it: and the exchange of it shall not be for jewels of fine gold. No mention shall be made of coral, or of pearls: for the price of wisdom is above rubies. The topaz of Ethiopia shall not equal it, neither shall it be valued with pure gold. Whence then cometh wisdom? and where is the place of understanding?”
As you can notice, in the quest for the original wisdom – like the search for our lost paradise – the prophet quotes only 2 countries: Ophir and Ethiopia. As we know from the I book of Kings 10,10-11:
“The queen of Sheba gave the king an hundred and twenty talents of gold, and of spices very great store, and precious stones: there came no more such abundance of spices as these which the queen of Sheba gave to king Solomon. And the navy also of Hiram, that brought gold from OPHIR, brought in from OPHIR great plenty of almug trees, and precious stones.”
Ophir was an ethiopian territory with golden mines, and also David prophetically speaks about Makeda saying:
“upon thy right hand did stand the queen in gold of Ophir”. (Psalm 45,9)
In this way, the prophet exalts the preciousness and wealth of the Ethiopian Motherland as supreme upon earth, and discreetly suggests the answer to his doubt. Wisdom came from the place where Adam lived in the beginning, where he met Egziabhier and was instructed by Him.
“The place whence wisdom cometh” means also the land whence Christ comes.
