Jeremiah 32:33

And they have turned unto me the back, and not the face: though I taught them, rising up early and teaching {them}, yet they have not hearkened to receive instruction. {back: Heb. neck}

They have turned their backs to me, and not their faces. Although I taught them, rising up early and teaching them, yet they have not listened to receive instruction.
