The Lord explains the watchman's task with an image: when the people of a land send a sentinel and he sees the sword coming, he blows the trumpet and warns. Whoever hears and ignores it is responsible for his own death; if the watchman does not warn, he is accountable for the people's blood. God makes Ezekiel watchman for Israel and asks him to pass on his warning faithfully to the wicked.
Then the prophet answers a lament of the people, who say that their sins weigh on them and they are wasting away. The Lord swears that he takes no pleasure in the death of the wicked, but in their turning from their way and living. The righteous will not be saved by past deeds if they turn from righteousness, and the wicked will not die for earlier sins if they repent and do what is right. The people charge that the Lord's way is not just, but God answers that it is their ways that are not.
In the twelfth year, the tenth month, on the fifth day, a fugitive comes to Ezekiel with the news that the city has been struck down. The evening before, the hand of the Lord had been on the prophet, and his mouth was opened before the messenger arrived. Those living in the ruins of Judah say that if Abraham, who was one man, inherited the land, they, being many, possess it; God answers that they will not possess it, because they eat with blood, worship idols and shed blood. Finally, the people listen to Ezekiel as to a beautiful song, but do not act on his words; when what he announced comes, they will know that a prophet has been among them.
