Contradiction with 1 Kings 10:6
The Queen of Sheba acknowledges Solomon's wisdom as true, but in 1 Kings 10:1, she doubted the reports initially, seeking to test him with hard questions.
1 Kings 10:6: And she said to the king, It was a true report that I heard in mine own land of thy acts and of thy wisdom. [report: Heb. word] [acts: or, sayings]
Contradiction with 2 Chronicles 9:1
The Queen of Sheba visits Solomon, hearing of his fame, consistent with 1 Kings 10:1, though here, it appears twice in the Bible, suggesting a contradiction in unique storytelling.
2 Chronicles 9:1: And when the queen of Sheba heard of the fame of Solomon, she came to prove Solomon with hard questions at Jerusalem, with a very great company, and camels that bare spices, and gold in abundance, and precious stones: and when she was come to Solomon, she communed with him of all that was in her heart.
