Isaiah 4

It took only 1 minute to read this very short passage. But I'm still stunbling over the meaning three parables, all speaking, I think, about three different views of the coming captivity. I think there is a hint of hope in this chapter; that there will be a rement that will remain in Jerusalem, and they will be called holy. And God will continue to provide for those of his people who come to him in humility. But I'm sure that there is a lot of figuretism that I'm missing.
