In whose holy book? Plenty of New Testament Biblical exegesis about the so-called "end times" involves things that could be interpreted as involving modern-day Israel (for example, the Jewish people returning to their homelands).
So: Jewish holy book? You're correct. Christian holy book? Answer is dependent on the sect of Christianity you are talking about.
Every Christian picks and chooses the parts of the Bible they want to follow, and then adds their own "interpretation" to it. So you get Christian sects with all sorts of beliefs.
The earliest Christians thought that Jesus would return while they were still alive.
Other people have read all kinds of things into the texts which aren't really there.
