2 Chronicles 1:15-17

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
A  shekel was about 2/5 ounce or 11 grams
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.
