us ... we

Here the words "us" and "we" refer to Isaiah and those to whom he spoke.

we would be like Sodom, and we would have become like Gomorrah

"we all would have been destroyed like the people of Sodom and Gomorrah" or "God would have destroyed all of us as he destroyed the people in the cities of Sodom and Gomorrah"
