Ezekiel 4:7 (KJV)

For I have laid upon thee the years of their iniquity, according to the number of the days, three hundred and ninety days: so shalt thou bear the iniquity of the house of Israel.

And when thou hast accomplished them, lie again on thy right side, and thou shalt bear the iniquity of the house of Judah forty days: I have appointed thee each day for a year.

Therefore thou shalt set thy face toward the siege of Jerusalem, and thine arm shall be uncovered, and thou shalt prophesy against it.

And, behold, I will lay bands upon thee, and thou shalt not turn thee from one side to another, till thou hast ended the days of thy siege.

Take thou also unto thee wheat, and barley, and beans, and lentiles, and millet, and fitches, and put them in one vessel, and make thee bread thereof, according to the number of the days that thou shalt lie upon thy side, three hundred and ninety days shalt thou eat thereof.
