She hath wearied herself with lies
With serving idols, which were lying vanities; by trusting to the alliances of neighbouring nations, which deceived her; or by committing sin, in which there was no satisfaction; or it may be understood of wearying of God with their sins, and particularly with her lying promises of repentance and reformation: and her great scum went not forth out of her;
notwithstanding her promises; or notwithstanding the admonitions given, and the chastisements inflicted on her, yet she continued hardened in her sins, impenitent and unreformed: her scum shall be in the fire;
like a pot that boils over, its scum falls into the fire, and is consumed there; and in no other way, but by the fire of divine judgments, or the burning of the city, could the wickedness thereof be consumed. The Targum is,
``and they shall not go out of her that work iniquity; in the fire shall she be burnt, because of the multitude of her sins.''
