Ezekiel 4:1-5

“Now you, son of man, take a brick, place it before you and inscribe on it [a diagram of] the city of Jerusalem. Then lay siege against it, build a siege wall, raise a ramp against it; set up [enemy] camps and place battering rams all around it. Further, take an iron plate and place it as an iron wall between you and the city, and set your face toward it so that it is under siege, and besiege it. This is a sign to the house of Israel. “Then lie down on your left side (toward the north) to bear [symbolically] the wickedness and punishment of the house of Israel. You shall bear their wickedness and punishment for the number of days that you lie on your side. For I have assigned you the years of their wickedness and punishment, according to the number of the days, three hundred and ninety days [representing three hundred and ninety years]; in this way you shall bear [symbolically] the wickedness and punishment of the house of Israel.
