1 Kings 10:26-29

Now Solomon collected chariots and horsemen; he had 1,400 chariots and 12,000 horsemen, which he stationed in the chariot cities and with the king in Jerusalem. The king made silver as common in Jerusalem as stones, and cedars as plentiful as the sycamore trees that are in the lowland. Solomon’s horses were imported from Egypt and from Kue, and the king’s merchants acquired them from Kue, for a price. [Deut 17:15, 16] A chariot could be imported from Egypt for six hundred shekels of silver, and a horse for a hundred and fifty; and in the same way they exported them, by the king’s merchants, to all the kings of the Hittites and to the kings of Aram (Syria).
