Ezekiel 4:5 In-Context

3 And 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; for the number of the days that you lie upon it, you shall bear their punishment.
5 For 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.
6 And 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.
7 And you shall set your face toward the siege of Jerusalem, with your arm bared; and you shall prophesy against the city.
