The fort. — The same word as strong hold in 2 Samuel 5:7.
Millo. — A word always used in Hebrew with the definite article (except in Judges 9:6; Judges 9:20), the Millo. It is probably an old Canaanitish name for the fortification on the northern end of Mount Zion, “inward” from which the palace was situated. Subsequent kings, as Solomon (1 Kings 11:27) and Hezekiah (2 Chronicles 32:5), saw its importance and added to its strength. On all other sides Zion was protected by precipitous ravines. There is, however, some difference of opinion about the topography of ancient Jerusalem.
