Jeremiah is speaking Yahweh's message to the people of Israel.

## Your injury is incurable...for your wound to heal you ##

This means that Yahweh has punished them so severely that there is no one that can help them. (See: [[rc://en/ta/man/translate/figs-metaphor]])

## There is no one to plead your case ##

AT: "There is no one who asks me to show you mercy"
