In The Crucible, what happens to Betty when she hears the Lord's name?

The answer to this question can be found in Act One of
this excellent play. As Abigail and Proctor stand over the catatonic Betty, the
congregation below begin to sing a psalm from the Bible. However, as the phrase "going
up to Jesus" is heard in the psalm, Betty claps her hands over her ears so she is unable
to hear the name of Jesus and begins whining loudly. This gradually escalates into
screaming. Of course, when the psalm is finished and Betty's father rushes into the
room, accompanied by the Putnams, this is seen as further evidence that some kind of
witchery has been going on, as Mrs. Putnam makes perfectly
clear:

The
psalm! The psalm! She cannot bear to hear the Lord's
name!

Thus it is that the
suspicions of witchery in Salem begin and are fuelled by Betty's response to hearing the
name of Jesus.
