Ezekiel 4:1-6New Revised Standard Version (NRSV)
The Siege of Jerusalem Portrayed
4 And you, O mortal, take a brick and set it before you. On it portray a city, Jerusalem; 2 and put siegeworks against it, and build a siege wall against it, and cast up a ramp against it; set camps also against it, and plant battering rams against it all around. 3 Then take an iron plate and place it as an iron wall between you and the city; set your face toward it, and let it be in a state of siege, and press the siege against it. This is a sign for the house of Israel.
4 Then lie on your left side, and place the punishment of the house of Israel upon it; you shall bear their punishment for the number of the days that you lie there. 5 For I assign to you a number of days, three hundred ninety days, equal to the number of the years of their punishment; and so you shall bear the punishment of the house of Israel. 6 When you have completed these, you shall lie down a second time, but on your right side, and bear the punishment of the house of Judah; forty days I assign you, one day for each year.
