41 And you, son of man, take a back and put it before you and on it make a picture of a town, even Jerusalem. 2 And make an attack on it, shutting it in, building strong places against it, and making high an earthwork against it; and put up tents against it, placing engines all round it for smashing down its walls. 3 And take a flat iron plate, and put it for a wall of iron between you and the town: and let your face be turned to it, and it will be shut in and you will make an attack on it. This will be a sign to the children of Israel. 4 Then, stretching yourself out on your left side, take the sin of the children of Israel on yourself: for as long as you are stretched out, so long will the sin of the children of Israel be on you. 5 For I have had the years of their sin measured for you by a number of days, even three hundred and ninety days: and you will take on yourself the sin of the children of Israel. 6 And when these days are ended, turning on your right side, you are to take on yourself the sin of the children of Judah: forty days, a day for a year, I have had it fixed for you. 7 And let your face be turned to where Jerusalem is shut in, with your arm uncovered, and be a prophet against it. 8 And see, I will put bands on you; and you will be stretched out without turning from one side to the other till the days of your attack are ended.

Commentary on Ezekiel 4:1-8
(Read Ezekiel 4:1-8)
The prophet was to represent the siege of Jerusalem by signs. He was to lie on his left side for a number of days, supposed to be equal to the years from the establishment of idolatry. All that the prophet sets before the children of his people, about the destruction of Jerusalem, is to show that sin is the provoking cause of the ruin of that once flourishing city.
