Millo: (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 Samuel 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
