Abigail: Uncle, we did dance; let you tell them i confessed it-- and I'll be whipped if i must be. But they're speakin of witchcraft. Betty's not witched.

When Abigail said this she was confessing that her and the girls were dancing in the woods naked around the fire. And she confessed the truth of what happened, and she would have to be whipped if she had to. But the town heard about what happened in the woods, and they were saying that Betty and Abigail were bewitched, and they were involved with witchcraft. And she told Parris that Betty wasn't witched.
