WE cannot tell exactly who the Queen of the South was,
nor exactly where Sheba lay. The expression used is Yemen, the south. Yemen is the name of a part of Arabia Felix and it would appear from the spices which the Queen brought with her that she came from that region. At the same time, the Abyssinians claim her as having been their queen. They say that she was converted through her conversations with Solomon, that afterwards the faith of God was preserved in the country, and hence that that famous Ethiopian, who was a eunuch of great authority under Candace in later times, was a proselyte to the Jewish faith on account of that faith existing in Abyssinia.
A Greater Than Solomon
[Sermon #3166 by Charles Spurgeon – published October 14, 1909]
And King Solomon gave to the queen of Sheba all that she desired, whatever she asked besides what was given her by the bounty of King Solomon. So she turned and went back to her own land with her servants. Now the weight of gold that came to Solomon in one year was 666 talents of gold, besides that which came from the explorers and from the business of the merchants, and from all the kings of the west and from the governors of the land.
1 Kings 10:13-15 [ESV]
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.
Job 28: 18-19 [KJV]
This calls for wisdom:
let the one who has understanding
calculate the number of the beast,
for it is the number of a man, and his number is 666.
