2 Chronicles 1:13-17
English Standard Version
14Solomon 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.
15And the king made silver and gold as common in Jerusalem as stone, and he made cedar as plentiful as the sycamore of the Shephelah.
16And Solomon 's import of horses was from Egypt and Kue, and the king 's traders would buy them from Kue for a price.
17They imported a chariot from Egypt for 600 shekels of silver, and a horse for 150. Likewise through them these were exported to all the kings of the Hittites and the kings of Syria.
