2 Chronicles 9:25-29

Now Solomon had four thousand stalls for horses and chariots and twelve thousand horsemen, and he stationed them in the chariot cities and with the king in Jerusalem.

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

And the king made silver as common as stones in Jerusalem, and he made cedars as plentiful as sycamore trees that are in the lowland.

And they were bringing horses for Solomon from Egypt and from all countries.

Now the rest of the acts of Solomon, from the first to the last, are they not written in the records of Nathan the prophet, in the prophecy of Ahijah the Shilonite, and in the visions of Iddo the seer concerning Jeroboam the son of Nebat?
