Which queen visited Solomon to test him with hard questions?

The queen who visited Solomon to test him with hard questions was indeed the queen of Sheba. This event is recounted in 1 Kings 10:1-2 and 2 Chronicles 9:1-2. The queen of Sheba traveled from her distant homeland, which is believed to be in the region that is now part of modern-day Yemen or Ethiopia, specifically to seek out Solomon's renowned wisdom and wealth.

Her visit was not merely a social call; she came with challenging questions, testing Solomon's legendary intellect. The narrative highlights Solomon's ability to answer all her questions satisfactorily, which emphasized his wisdom as a gift from God. Additionally, her visit serves to illustrate the extent of Solomon's fame, as people from far regions were drawn to his court.

The other queens mentioned do not have a similar narrative in the Old Testament where they challenge Solomon with questions. The queen of Egypt and the queen of Babylon do not appear in stories related to testing Solomon’s wisdom, and Queen Esther’s story is entirely separate, focusing on her role in the Persian court rather than interactions with Solomon.
