The Millo was a structure in Jerusalem referred to in the Hebrew Bible, first mentioned as being part of the city of David in 2 Samuel 5:9 and the corresponding passage in the Books of Kings and later in the Books of Chronicles. However it previously seems to have been a rampart built by the Jebusites prior to Jerusalem's being conquered by the Israelites. The texts also describe the Millo built by Solomon and repaired by Hezekiah, without giving an explanation of what exactly the Millo was: there is therefore some debate among scholars as to the Millo's specific nature. The most common assumption among archaeologists and historians of ancient Israel is that the Millo is the Stepped Stone Structure uncovered by Kathleen Kenyon and demonstrated by Eilat Mazar to be connected to a Large Stone Structure which she discovered in 2005.

Solomon, also called Jedidiah, was a monarch of ancient Israel and the son and successor of King David, according to the Hebrew Bible or Old Testament. He is described as having been the penultimate ruler of an amalgamated Israel and Judah. The hypothesized dates of Solomon's reign are from 970 to 931 BCE. After his death, his son and successor Rehoboam would adopt a harsh policy towards the northern tribes, eventually leading to the splitting of the Israelites between the Kingdom of Israel in the north and the Kingdom of Judah in the south. Following the split, his patrilineal descendants ruled over Judah alone.
