What does Isaias Chapter 19 say, and which statements belong to its speaker?

Isaias 19 portrays the Lord entering Egypt on a swift cloud. Idols move, hearts melt, and Egyptians fight brother, friend, city and kingdom. Broken spirit and counsel lead to consulting idols, diviners, wizards and soothsayers; cruel masters and a strong king receive rule. The sea and river dry, streams diminish, reeds and bulrushes wither, planted growth disappears, and fishers, flax workers, linen weavers and fish-pool makers mourn.

Tanis and Memphis's princes give foolish counsel. Claimed descent from wise men and kings cannot reveal the Lord's purpose. A spirit of giddiness makes Egypt err like a staggering, vomiting drunkard; no work remains. Egypt is compared with frightened women, and Juda becomes a terror because of the Lord's counsel. These are the oracle's comparisons, without modern medical diagnosis or a named foreign king.

Five cities speak Chanaan's language and swear by the Lord; one is the city of the sun. An altar and boundary monument provide a sign and testimony. Oppression prompts cries and the promised Saviour and defender. Egyptians know the Lord, offer sacrifices and fulfill vows. He strikes and heals, and they return. A way connects Egypt and Assyria, with reciprocal travel and Egyptians serving the Assyrian. Israel is third, a blessing in the land. Egypt is called my people, Assyria the work of my hands, Israel my inheritance. Shared blessing is not substituted for the distinct service wording or expanded into worldwide institutional communion.
