1 Kings 4:34 (ESV)

34 And people of all nations came to hear the wisdom of Solomon, and from all the kings of the earth, who had heard of his wisdom.

The chapter, as we have observed in connection with 1 Kings 4:31, reveals the result of Solomon’s international fame. The writer informs us that people came from many nations to hear his wisdom. The text uses the word all nations and all kings. This may be an exercise of hyperbole, a literary device that uses overstatement to make a point. In these cases the reader is not supposed to take the statement as absolutely literal. It is a way of speaking so that we understand that many of the surrounding nations (and perhaps all of them, since many were under the control of Israel) travelled to hear Solomon’s wisdom first-hand. A later chapter gives us one example as the writer records the visit of the Queen of Sheba.
