Why does Elizabeth say, on page 55, that where Abigail waslks' the crowd will part like the sea for Israel'?What is she saying about Abigail?

Elizabeth alludes to the fact that people believe everything Abigail says. You need to look at the entire quote in context, what Elizabeth is saying is that the "black magic" or witchcraft isn't coming from the accused, but rather from the one instigating the hysteria.

"The Deputy Governor promise hangin’ if they’ll not confess, John. The town’s gone wild, I think. She speaks of Abigail, and I thought she were a saint, to hear her. Abigail brings the other girls into the court, and where she walks the

crowd will part like the sea for Israel. And folks are brought before them, and if they scream and howl and fall to the floor - the person’s clapped in the jail for bewitchin’ them."
