The Lord is exalted - (compare Psalms 97:9). The prophet here introduces a chorus of the Jews, celebrating the praises of God for delivering them from the Assyrian.
He hath filled Zion with judgment - That is, the effect of his destroying his enemies will be to fill Jerusalem with reverence for his name. The deliverance would be so signal, and the manifestation of the divine mercy so great, that the effect would be that the nation would turn to God, and acknowledge his gracious interposition (see Isaiah 30:22-26, Isaiah 30:29; Isaiah 31:6; Isaiah 32:15-18).
