2 Chronicles 9:25-28

25Now Solomon had 4,000 stalls for horses and chariots, and 12,000 horsemen, and he stationed them in the chariot cities or with the king at Jerusalem.

26He ruled over all the kings from the Euphrates River to the land of the Philistines, and as far as the border of Egypt.

27The king made silver in Jerusalem as common as stones, and cedar wood as plentiful as the sycamore-fig trees that are in the lowland.

28And they were importing horses for Solomon from Egypt and from all [the other] countries.
