What does Lamentations 2:1-10 mean?

How the Lord in his anger has set the daughter of Zion under a cloud! He has cast down from heaven to earth the splendor of Israel; he has not remembered his footstool in the day of his anger. The Lord has swallowed up without mercy all the habitations of Jacob; in his wrath he has broken down the strongholds of the daughter of Judah; he has brought down to the ground in dishonor the kingdom and its rulers. He has cut down in fierce anger all the might of Israel; he has withdrawn from them his right hand in the face of the enemy; he has burned like a flaming fire in Jacob, consuming all around. He has bent his bow like an enemy, with his right hand set like a foe; and he has killed all who were delightful in our eyes; in the tent of the daughter of Zion, he has poured out his fury like fire. The Lord has become like an enemy; he has swallowed up Israel; he has swallowed up all its palaces; he has laid in ruins its strongholds, and he has multiplied in the daughter of Judah mourning and lamentation. He has laid waste his booth like a garden, laid in ruins his meeting place; the LORD has made Zion forget festival and Sabbath, and in his fierce indignation has spurned king and priest. The Lord has scorned his altar, disowned his sanctuary; he has delivered into the hand of the enemy the walls of her palaces; they raised a clamor in the house of the LORD as on the day of festival. The LORD determined to lay in ruins the wall of the daughter of Zion; he stretched out the measuring line; he did not restrain his hand from destroying; he caused rampart and wall to lament; they languished together. Her gates have sunk into the ground; he has ruined and broken her bars; her king and princes are among the nations; the law is no more, and her prophets find no vision from the LORD. The elders of the daughter of Zion sit on the ground in silence; they have thrown dust on their heads and put on sackcloth; the young women of Jerusalem have bowed their heads to the ground.
