After King Jehoiakim burned Jeremiah's scroll, what did Jeremiah do?

Answer: Had Baruch write a new scroll

Jeremiah gave another scroll to Baruch, who wrote at his dictation all the words of the burned scroll, and many similar words were added.

“Then Jeremiah took another scroll and gave it to the scribe Baruch son of Neriah, and at Jeremiah’s dictation he wrote on it all the words of the scroll that Jehoiakim king of Judah had burned in the fire. And many similar words were added to them.”— Jeremiah 36:32 (BSB)
