God summons six executioners to kill the people in Jerusalem, including a figure dressed in linen with a writing case.
The executioners come in and stand by the Temple altar, while God gives them their orders.
God tells the man with the writing case to mark the people who going to survive off from those doomed for destruction. The survivors are those who turn away from the abominations. The writing case guy will mark them on the foreheads.
The executioners will then go through the city and kill everyone who doesn't have the mark, everyone from the youngest children to the oldest men and women.
First, the executioners kill the corrupt elders in God's sanctuary, before moving into the city.
Ezekiel prostrates himself and asks God if he'll kill as many people in the rest of Judah as he has in Jerusalem.
God says yeah, no pity.
At the end of the chapter, the man with the writing case returns and says he's accomplished his mission.
