A). EXODUS means the departure of the children of Isrealites out of Egpyt... It literarily connotes departure, to go out, leave, migration etc of a large number of people... It a Greek word ek'-so-dus...
B). The book refer to as revelation in the old testament ...... Hmmmn..... I go for DANIEL... Because, the book of Revelation is an example of "apocalyptic" writing - a form that delivers a message using symbols, images and numbers. Parts of the Old Testament, particularly in the book of Daniel, are also written in the apocalyptic genre. Many of the symbols and images in Revelation have parallels in the Old Testament...
Hmmmm....
