1 Kings 10:26-29

And Solomon gathered together chariots and horsemen. He had 1,400 chariots and 12,000 horsemen, whom he stationed in the chariot cities and with the king in Jerusalem. And the king made silver as common in Jerusalem as stone, and he made cedar as plentiful as the sycamore of the Shephelah. And Solomon’s import of horses was from Egypt and Kue, and the king’s traders received them from Kue at a price. A chariot could be imported from Egypt for 600 shekels of silver and a horse for 150, and so through the king’s traders they were exported to all the kings of the Hittites and the kings of Syria.
