Hi, I am looking for some biblical allusions in the grapes of wrath, herman melville's Moby , and Hamlet. Can you help me?

Probably if you Google the titles and add Biblical References, you'll get something.

"...east of Eden" itself is from Genesis.

Moby , many of the main characters' names, Ahab, Ishmael, Elijah, etc are from The Bible.

Hamlet says, "there's a special providence in the fall of a sparrow"---this too iclose to a Bible quote, but I can't help you on which book and line.
