Ezekiel 4:5-6

5For 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.

6When you have completed these [days for Israel], lie down again, but on your right side (toward the south), and you shall bear the wickedness and punishment of the house of Judah forty days. I have assigned you one day for each year.
