2 Chronicles 1:14-17

Solomon had fourteen hundred chariots and twelve thousand horses. He kept some in special cities for the chariots, and others he kept with him in Jerusalem. In Jerusalem Solomon made silver and gold as plentiful as stones and cedar trees as plentiful as the fig trees on the western hills. He imported horses from Egypt and Kue; his traders bought them in Kue. They imported chariots from Egypt for about fifteen pounds of silver apiece, and horses cost nearly four pounds of silver apiece. Then they sold the horses and chariots to all the kings of the Hittites and the Arameans.
