You've in Graven, Look at the End of Verse 1 of Chapter 17

The sin of Judah is written with a pen of iron and with the point of a diamond. It's graven upon the table or hearts and upon the horns of your altars. Jeremiah uses very strong language about the near permanency of what the people's actions had done. But we need to remember that God still is calling to them, wanting them back in this relationship.
