(Heb. always with the article, “the” Millo). (1.) Probably the Canaanite name of some fortification, consisting of walls filled in with earth and stones, which protected Jerusalem on the north as its outermost defence. It is always rendered Akra i.e., “the citadel”, in the LXX. It was already existing when David conquered Jerusalem (2 Sam. 5:9). He extended it to the right and left, thus completing the defence of the city. It was rebuilt by Solomon (1 Kings 9:15, 24; 11:27) and repaired by Hezekiah (2 Chr. 32:5).

(2.) In Judg. 9:6, 20 it is the name of a rampart in Shechem, probably the “tower of Shechem” (9:46, 49).

(a rampart, mound) a place in ancient Jerusalem. Both name and place seem to have been already in existence when the city was taken from the Jebusites by David. (2 Samuel 5:9; 1 Chronicles 11:8) Its repair or restoration was one of the great works for which Solomon raised his “levy,” (1 Kings 9:15,24; 11:27) and it formed a prominent part of the fortifications by which Hezekiah prepared for the approach of the Assyrians. (2 Chronicles 32:5) The last passage seems to show that “the Milo” was part of the “city of David,” that is, of Zion. Comp. (2 Kings 12:20)
