'Lonely' in the Bible

The Israelites ascribed things to the Lord their God which were not true. They built for themselves high places [of worship] in all their towns, from [the lonely] lookout tower to the [populous] fortified city.

Turn to me [Lord] and be gracious to me,For I am alone and afflicted.

How solitary and lonely sits the city [Jerusalem]That was [once] full of people!How like a widow she has become.She who was great among the nations!The princess among the provinces,Has become a forced laborer!
