Isaiah continues speaking.

## Therefore he ##

"Therefore Yahweh"

## against them ##

Here "them" refers to the people of Israel, but Isaiah still included himself as part of the people. AT: "against us"

## It blazed around them...it burned them ##

Isaiah describes Yahweh's anger as a fire to emphasize its power to destroy. (See: [[rc://en/ta/man/translate/figs-metaphor]])
