2 Chronicles 1:15-17
1:15 The king made silver and gold as plentiful in Jerusalem as stones; cedar was as plentiful as sycamore fig trees are in the lowlands.
1:16 Solomon acquired his horses from Egypt and from Que; the king’s traders purchased them from Que.
1:17 They paid 600 silver pieces for each chariot from Egypt, and 150 silver pieces for each horse. They also sold chariots and horses to all the kings of the Hittites and to the kings of Syria.
