mil'-o. (millo generally interpreted to mean a "filling," e.g. a solid tower or an earth embankment; in Judges 9:6,20; 2 Kings 12:20, we get beth millo', translated in English Versions of the Bible "House of Millo," which Winckler thinks may have been the original Jebusite temple-shrine of Jerusalem (see BETH-MILLO); Septuagint reads Bethmaalon, also Maalon and oikos Maallon):
1. Old Testament References
It is generally supposed that "The Millo" was some kind of fortress or other defense, but many speculations have been made regarding its position. In 2 Samuel 5:9, we read that David built round about from the Millo and inward, or (in the Septuagint, Septuagint) "he fortified it, the city, round about from the Millo and his house" (compare 1 Chronicles 11:8). In connection with Solomon's strengthening of the fortifications, there are several references to Millo. In 1 Kings 9:15, Solomon raised a levy "to build the house of Yahweh, and his own house, and Millo, and the wall of Jerusalem," etc.; in 9:24, "Pharaoh's daughter came up out of the city of David unto her house which Solomon had built for her:
then did he build Millo"; in 1 Kings 11:27, Solomon "built Millo, and repaired the breach of the city of David his father." At a later time Hezekiah "took courage, and built up all the wall that was broken down, and raised it up to the towers, and the other wall without, and strengthened Millo in the city of David" (2 Chronicles 32:5; 2 Kings 12:20); Joash was slain by his servants "at the house of Millo, on the way that goeth down to Silla," but possibly this may have been in Shechem (compare Judges 9:6).
2. Identical with the Akra Site:
The mention of the site in the days of David and the reference to it in connection with the city of David (1 Kings 11:27) point to some part of the southeastern hill South of the temple. It is suggestive that Millo is in Septuagint always translated by "Akra." It seems to the present writer very probable that it was a fortress crowning the hill on which at a later time stood the Syrian Akra, which hill, if we are to believe Josephus (BJ, V, iv, 1, etc.), was cut down because its commanding situation dominated the temple. This hill cannot have been the site of Zion afterward known as "David's Burg" (City of David), because the tombs of the Judean kings were within its walls, and that alone would have made the complete leveling of the site impossible, but whereas the Jebusite fortress was probably not far from Gihon, this fortified summit may have been, as Watson suggests for the Akra, as far north as where the present Al Aqsa mosque is situated. In David's time it may have been an isolated and detached fort guarding the north approach, but if it was originally a Jebusite high place (Winckler) partly of sun-dried brick like similar constructions in Babylonia, the account of its being leveled would be much more credible. The importance of this site in the days of Solomon is fully explicable if this was the citadel guarding the newly built temple and royal palaces.
Dr. G.A. Smith is inclined to think that Millo may have been a fortress "off the south end of Ophel, to retain and protect the old pool," and Vincent suggests that the site of Millo is that now occupied by the great causeway connecting the Western and Eastern hills along which runs the Tariq bab es silsileh.
