Jamieson, Fausset and Brown on 1 Kings 10:6

6. It was a true report that I heard in mine own land of thy acts and of thy wisdom--The proofs she obtained of Solomon's wisdom--not from his conversation only, but also from his works; the splendor of his palace; the economy of his kitchen and table; the order of his court; the gradations and gorgeous costume of his servants; above all, the arched viaduct that led from his palace to the temple (2Ki 16:18), and the remains of which have been recently discovered [Robinson]--overwhelmed her with astonishment. [See on 2Ch 9:4.]
