What are the Bible references in Grapes of Wrath?

Answer 1

There are many references:

The land is dead and produces no crops, perhaps a reference to Cain's punishment for killing Abel when God ordained that nothing will grow upon the crops which he works (ref: Genesis)

The book's main metaphor, the "Grapes of Wrath," is a reference to Revelations ("The cup of iniquity is full, the grapes of wrath are ripe, and now God crushes them in awesome judgment. Those who have rejected His grace feel the terror of His wrath.")

There is a flood by the end (ref: 40 days and 40 nights of Genesis)

Jim Casy sacrifices himself and struggles with religion and organized authority (ref: Jesus Christ)

Uncle John puts Rose of Sharon's baby in a box and sends it down the river (ref: Moses)
