Take thou unto thee an iron pan - מחבת machabath, a flat plate or slice, as the margin properly renders it: such as are used in some countries to bake bread on, called a griddle or girdle, being suspended above the fire, and kept in a proper degree of heat for the purpose. A plate like this, stuck perpendicularly in the earth, would show the nature of a wall much better than any pan could do. The Chaldeans threw such a wall round Jerusalem, to prevent the besieged from receiving any succours, and from escaping from the city.
This shall be a sign to the house of Israel - This shall be an emblematical representation of what shall actually take place.
An iron pan - Another figure in the coming siege. On Assyrian sculptures from Nimroud and Kouyunjik there are sieges of cities with “forts, mounts, and rams;” and together with these we see a kind of shield set up on the ground, behind which archers are shooting. Such a shield would be represented by the “flat plate” (margin). Ezekiel was directed to take such a plate (part of his household furniture) and place it between him and the representation of the city.
A sign to the house of Israel - This “sign” was not necessarily acted before the people, but may simply have been described to them as a vivid representation of the event which it foretold. “Israel” stands here for the kingdom of Judah (compare Ezekiel 3:7, Ezekiel 3:17; Ezekiel 5:4; Ezekiel 8:6). After the captivity of the ten tribes the kingdom of Judah represented the whole nation. Hence, prophets writing after this event constantly address their countrymen as the house of Israel without distinction of tribes.
