Towers
American Tract Society Bible Dictionary [1]
Were erected not only in the outer walls and on the heights within cities, Judges 9:47-49 Psalm 48:12 Luke 13:4 , but along the frontiers of a country, at points where the approach of an enemy could be descried at a distance, Judges 9:17 Isaiah 21:6-9 Ezekiel 33:2-6 . A tower afforded a refuge to the surrounding inhabitants, in case of invasion; and often, when most of a city was subdued, the tower or citadel remained impregnable.
So God is a strong and safe protector of his people, Psalm 18:2 61:8 Proverbs 18:10 . A slight tower or look-out was often erected for the keeper of a vineyard or flock, 2 Chronicles 26:10 Isaiah 5:2 Micah 4:8 Matthew 21:33; and travelers in Palestine see them in use at this day.
