Charles Spurgeon Commentary 1 Kings 10:2

"And she came to Jerusalem with a very great train, with camels that bare spices, and very much gold, and precious stones; and when she was come to Solomon, she communed with him of all that was in her heart." — 1 Kings 10:2 (ASV)

She came with a price in her hand to get wisdom. Solomon rightly said, "Buy the truth, and sell it not." No price is too dear to pay for it, but any price would be too cheap to sell it at.
