Ezekiel 4:6-8

6And when thou hast accomplished them, thou shalt 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.

7And thou shalt set thy face toward the siege of Jerusalem, and thine arm shall be uncovered, and thou shalt prophesy against it.

8And behold, I lay bands upon thee, and thou shalt not turn thyself from one side to the other, till thou hast ended the days of thy siege.
