1 Kings 9:24

Nevertheless, David captured the fortress of Zion, that is the city of David.

Then David lived in the fortress and called it the city of David. And David built all around from the Millo and inward.

Then Solomon formed a marriage alliance with Pharaoh king of Egypt, and took Pharaoh’s daughter and brought her to the city of David until he had completed building his own house and the house of Yahweh and the wall around Jerusalem.

Now his house where he was to live, the other court inward from the hall, was of the same workmanship. He also made a house like this hall for Pharaoh’s daughter, whom Solomon had married.

Now this is the account of the forced labor which King Solomon raised up to build the house of Yahweh, his own house, the Millo, the wall of Jerusalem, Hazor, Megiddo, and Gezer.

Now this was the reason why he raised his hand against the king: Solomon built the Millo, and closed up the breach of the city of his father David.

Now it happened at the end of the twenty years in which Solomon had built the house of Yahweh and his own house

And he strengthened himself and rebuilt all the wall that had been broken down and erected towers on it, and built another outside wall and strengthened the Millo in the city of David, and made weapons and shields in great number.
