CHAPTER 4 Sep. 3 
Terrible Suffering in Jerusalem
How the gold has become dim! The most pure gold has changed! The stones of the sanctuary are poured out at the head of every street. 2The precious sons of Zion, comparable to fine gold, how are they now esteemed as earthen pitchers, the work of the hands of the potter! 3Even the jackals draw out the breast, they nurse their young ones: the daughter of my people has become cruel, like the ostriches in the wilderness. 4The tongue of the nursing child clings to the roof of his mouth for thirst: the young children ask bread, and no man breaks it to them. 5Those who fed delicately are desolate in the streets: those who were brought up in scarlet embrace dunghills. 6For the punishment of the iniquity of the daughter of my people is greater than the sin of Sodom, that was overthrown as in a moment, and no hands were laid on her. 7Her nobles were purer than snow, they were whiter than milk; they were more ruddy in body than rubies, their polishing was as of sapphire. 8Their appearance is blacker than a coal; they are not known in the streets: their skin clings to their bones; it is withered, it has become like a stick. 9Those who are killed with the sword are better than those who are killed with hunger; for these pine away, stricken through, for want of the fruits of the field. 10The hands of the pitiful women have boiled their own children; they were their food in the destruction of the daughter of my people.
God's Anger Poured Out 
11Yahweh has accomplished His wrath, He has poured out His fierce anger; He has kindled a fire in Zion, which has devoured its foundations. 12The kings of the land didn’t believe, neither all the inhabitants of the world, that the adversary and the enemy would enter into the gates of Jerusalem. 13It is because of the sins of her prophets, and the iniquities of her priests, that have shed the blood of the just in the midst of her. 14They wander as blind men in the streets, they are polluted with blood, so that men can’t touch their garments. 15Depart! they cried to them, Unclean! Depart, depart, don’t touch! When they fled away and wandered, men said among the nations, They shall not live here any more. 16The anger of Yahweh has scattered them; He will no more regard them: they didn’t respect the persons of the priests, they didn’t favour the elders. 17Our eyes still fail, looking in vain for our help: in our watching we have watched for a nation that could not save. 18They hunt our steps, so that we can’t go in our streets: our end is near, our days are fulfilled; for our end has come. 19Our pursuers were swifter than the eagles of the sky: they chased us on the mountains, they laid wait for us in the wilderness. 20The breath of our nostrils, the anointed of Yahweh, was taken in their pits; of whom we said, Under His shadow we shall live among the nations. 21Rejoice and be glad, daughter of Edom that dwells in the land of Uz: the cup shall pass through to you also; you shall be drunken, and shall make yourself naked. 22The punishment of your iniquity is accomplished, daughter of Zion; He will no more carry you away into captivity: He will visit your iniquity, daughter of Edom; He will uncover your sins.

Commentary

4:6 By an interesting metonymy in the Hebrew language, the idol, the thing that facilitated sin, is put for their punishment / ruin. Sin and the punishment for it are inextricably linked. The Hebrew language reflects this identity here too, in that the Hebrew word for “punishment” is the same as for “iniquity”. And so it is with all the things of this present evil world; movies, music, novels, the needle, the bottle.... there is nothing unclean in itself, but these things can all be put by metonymy for the condemnation that can arise from the sin they facilitate. It's a powerful thought, as we face hourly temptation.
4:11 Both Yahweh and Israel are described as kindling the fire of judgment; He responded to what they had done (Jer. 11:16; 15:14; Lam. 4:11 cp. Jer. 17:4). Those who will be condemned will be only those who really wanted it.
4:15 Israel were made to depart into captivity because of their self-righteous rejection of their brethren, telling them to ‘depart’ from them because they considered them unclean- when they themselves were unclean.
