An iron pan. Heb. machabath, a sort of flat plate, a common cooking utensil in the East (see Lev. 2:5). The griddle may have formed part of the furnishings of the prophet’s own house. It was used to represent a shield or defense wall set up by the enemy, from behind which they discharged their missiles. The iron probably symbolized the invulnerability of the enemies’ lines.
A sign. The fact that these dramatic enactments were to constitute a “sign” lends strong support to the view that this chapter speaks of literal events (see on v. 1). For the word “sign” see on Isa. 7:14.
