At that time the city of the world ( Isaiah 24:10; Isaiah 24:12; Isaiah 25:2), notable for its fortifications, will lie overthrown and isolated. Some premillennialists regard this as a reference to the destruction of Jerusalem in586 B.C. [1][source]
"Ruins testify to a commercial and militaristic civilization that has now become quietly pastoral." [2][source]
The prophet pictured the deserted condition of that city: calves grazing there and stripping the vegetation without human restraint, and women gathering dry wood for fires. Normally these activities took place outside cities. Dry limbs reflect a desolate condition since normally trees in cities were alive. The reason for the destruction of this city is that its inhabitants did not have discernment. They did not see their need to humble themselves and submit to God, even though He took great care to form them as His creatures. [source][source][source]
