Truth having been ignored, the end result is captivity, immense suffering, immense humiliation, phenomenal lamentation and grief, great anxiety and depression, and that is exactly what is being portrayed here.
Her and she, is a reference to Jerusalem. The city is often referred to in the feminine being distinguished for its beauty and attributes that are distinctly feminine. Song of Solomon is a detailed study of the desirability and intense affection portrayed of the female and her features.
However, when truth is rejected, then beauty and desirability evaporates and is replaced with a picture of a captive woman sitting in the dust, beauty lost, feminine attributes vanished, and replaced with tremendous humiliation, grief, and sorrow. Not only for the loss of the men as described in the previous verse, but for her own feminine attributes of beauty and seductivity, that have been described in many of the previous verses.
And having been warned over and over, again and again, the people, especially believers, consciously turned away from God and truth, and turned proactively toward lies, worldliness, external beautification accessories, and so forth, to the exclusion of their own soul.
Jerusalem and Judah was referred to way back since the first verse. The city and region having been filled with spiritually negative people, replacing and diminishing the numbers of those who were positive. As well as replacing and diminishing truth and all that accompanies it.
The city gates represent the commerce and life flow of a city. This commerce and life, have ceased.
The public sitting on the ground, represents the captive posture of extreme humiliation and extreme sorrow.
The feminine gender represents the soft and desirable and beauty attributes of what should be, but now are not.
The result, a helpless and humiliating situation of the worst possible kind imaginable. In war the men are brutally tortured and killed, while the women who remain alive, are ravaged repeatedly with no one to come to their aid, because there is no one available to come to their aid.
This is the picture. This is the price paid when doctrine is disregarded.
These historical events and circumstances have occurred in the past and continue to exist in varying degrees, even in our present day in some parts of the world, but the ultimate and by far the worst events of history, will occur in gruesome detail during and at the end of the tribulation, which is still future. And all because a world society simply rejects truth.
