Ellicott's Commentary On The Whole Bible
1 Kings 9:15
The levy. — This (see 1 Kings 5:13; 1 Kings 5:15) was both of Israelites and of the subject races, first originated for the building of the Temple, afterwards extended to the other great building works.
The building works enumerated are, first in Jerusalem, then in various parts of the country of critical importance, either for war or for commerce.
Millo, or (as it always has the definite article), “the Millo.” The Hebrew word seems to signify “piling up,” or “heaping up,” and its most simple meaning would be a “fortified mound.” From the mention, however, in Judges 9:6; Judges 9:20, of the “house of Millo,” in connection with the men of Shechem, it has been supposed to be a Canaanitish word; and it is possible that “the Millo” of Jerusalem may have been the name of a quarter of the old Jebusite city, especially as it is first used in connection with the narrative of its capture (2 Samuel 5:9; 1 Chronicles 11:8). That it was a part of the fortification of “the city of David” is clear by this passage, by 1 Kings 9:24 and 1 Kings 11:27, and by 2 Chronicles 32:5; and the LXX. invariably renders it “Acra,” or “the-citadel,” a name always applied in the later history to the fortification on Mount Zion. Josephus, in describing the works of Solomon, merely says that he made the walls of David higher and stronger, and built towers on them. From the derivation of the word it is possible that the work was the raising a high fortification of earth crowned with a wall, where the hill of Zion slopes down unto the valley known subsequently as the Tyropœon.
Hazor, Megiddo, and Gezer. — These cities were all of important geographical positions, and all had belonged to the subject races.
Hazor was in the north, on high ground near the waters of Merom. It had been the city of Jabin, head of the northern confederacy (Joshua 11:1). After the great victory over this confederacy, Joshua burnt Hazor (Joshua 11:13), and the territory was assigned to Naphtali (Joshua 19:36). But it must have been regained by its old possessors, and rebuilt, for it appears again under another Jabin in Judges 4. It was evidently important, as commanding the great line of invasion through Hamath from the north. Hence it was fortified by Solomon, and probably the native inhabitants were dispossessed.
Megiddo lay in the great plain of Jezreel or Esdraelon, the battle-field of Northern Palestine, commanding some of the passes from it into the hill country of Manasseh, to which tribe it was assigned after the conquest (Joshua 17:11). But it was not subdued by them (Joshua 17:12; Judges 1:27), and, with Taanach, appears as a hostile city in the Song of Deborah (Judges 5:19). Now it was fortified, and is named subsequently as an Israelite city (2 Kings 9:27; 2 Kings 23:29). In later times the Romans seem to have occupied it, and their name for it, Legio (now el-Łejjûr), superseded the old title.
Grezer or Gazer, was near Bethlehem, close to the maritime plain. Its king was conquered by Joshua (Joshua 10:33; Joshua 12:12), and the city was allotted to the Levites in the territory of Ephraim (Joshua 21:17), but it remained unsubdued (Judges 1:29). From the notice in the next verse, it must have been in rebellion against Israel, perhaps in the early and more troubled days of Solomon; and was accordingly taken by the Egyptian army (which could easily march up the plain, and attack it therefrom). The passes here were of critical importance, as appears in the Philistine wars (1 Chronicles 20:4; 2 Samuel 5:25), in relation to any advance from the plain.
