4:3 Moreover take thou to thee an {a} iron pan, and set it [for] a wall of iron between thee and the city: and set thy face against it, and it shall be besieged, and thou shalt lay siege against it. This [shall be] a sign to the house of Israel.
(a) Which signified the stubbornness and hardness of their hearts.
4:3 A wall - That it may resemble a wall of iron, for as impregnable as such a wall, shall the resolution and patience of the Chaldeans be.
4:1-8 The prophet was to represent the siege of Jerusalem by signs. He was to lie on his left side for a number of days, supposed to be equal to the years from the establishment of idolatry.
