These descriptions all apply to the destruction of the first Temple and the troubles that came along with. And on this Ivoy (3:5) says about the day of his birth "may darkness and gloom claim it and a cloud lie on it". And maybe it is a hint to the day that is decreed for our troubles that is the 9th of Av.

The word in the pasuk "shachar" is from the root of the word "black" and therefore the daybreak is called "shachar" because the light has not yet started to spread on the world. And the meaning is the darkness hints to a great multitude of a nation that Nevuchad nezer brought to Jerusalem that was great in number and mighty in stregnth and there was never before like it in the world and never again afterwards for gerenations. This means that from the time the world was created, no nation had ever gone to war with such a great and mighty army like him and afterwards this will never be for generations. even the army led by Titus to destoruy the second Temple was much larger than Nevud Nezers and therefore it says "for generations" since Titus's army was many generations later after 500 years.
