Ezekiel 4:2–8

²and put siegeworks against it, and build a siege wall against it, and cast up a mound against it; set camps also against it, and plant battering rams against it round about. ³And take an iron plate, and place it as an iron wall between you and the city; and 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 upon your left side, and I will lay the punishment of the house of Israel upon you;ⁿ for the number of the days that you lie upon it, you shall bear their punishment. ⁵For I assign to you a number of days, three hundred and ninety days, equal to the number of the years of their punishment; so long shall you bear the punishment of the house of Israel. ⁶And 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, a day for each year. ⁷And you shall set your face toward the siege of Jerusalem, with your arm bared; and you shall prophesy against the city. ⁸And, behold, I will put cords upon you, so that you cannot turn from one side to the other, till you have completed the days of your siege.
