I am trying to remember a scary movie from the 60s or 70s. I believe it was about a coven of witches. I just remember a couple and that the woman ends up succumbing to the coven and the husband getting his tongue cut out at the end of the movie but he lives. The last seen I recall is the husband rocking in a wooden rocker looking out a large bay window. Please help! Obsessed for years trying to figure this out.
