I thought Jesus told the disciples to go to the "hebrews" first. Paul is the one who shifted that narrative to expand to gentiles.
as for the Bible its the story of a group of people who an ancient race chose to be their messengers, they failed at every attempt and then were punished, the reason for this ties back to stories in the sumerian sagas, they tried again with Jesus an those people who were chosen killed him instead. The book of revelation i have no clue, part of me thinks its early fear propaganda that was used to direct history in a certain way, much like the protocols.
