The answer is: 120 talents of gold, spices, and precious stones

1 Kings 10:2 - The Queen of Sheba's visit to Solomon was not only to test his wisdom but also a recognition of his wealth and God's favour. Her extravagant gifts underscore the opulence of Solomon's reign, highlighting the connections to the wealth mentioned in Proverbs 3:16 and 1 Chronicles 29:28.

The visit of the Queen of Sheba is not just a moment of royal diplomacy, it's a showcase of the splendor of Solomon’s kingdom and the wisdom that was famed far and wide. When she arrived, bringing along a staggering 120 talents of gold, a vast array of spices, and precious stones, it was truly emblematic of the prosperity that surrounded Solomon’s reign. This wealth was significant; a talent is approximately 75 pounds, which means she gifted him roughly 9,000 pounds of gold!

In addition to the practical symbols of wealth, her gifts represented a deeper intrigue with Solomon’s wisdom, suggesting cultural and intellectual exchanges. The Queen sought knowledge, testing the limits of Solomon's acclaimed sagacity—all this happening against the backdrop of ancient trade routes that linked Sheba, believed to be in the area of modern-day Yemen, with the riches of Israel.

Echoing Proverbs 3:16, where wisdom is personified as bringing long life and riches, her visit fittingly illustrates how wisdom and wealth often walked hand in hand in the biblical narrative. The alliance of beauty in riches with wisdom also reflects themes present in literature across cultures, suggesting a universal pursuit of knowledge—wasn't she more than just a queen; she was also a seeker?

Interestingly, Solomon’s interactions paved the way for future engagements and stories, entwining the destinies of various tribes and nations. From this narrative bloom countless echoes of the importance of pursuing wisdom above material wealth, a timeless reminder that transcends generations.
