Why will the Palestinians have to find a new home?

Les explains that God is bringing the Jews back to Palestine, and this is happening right before our eyes. He says the poor Arabs have their homes and businesses there, but something is going to have to happen because that land belongs to the Israelites, and they are going to get it. Les does not know how it will happen, but he expects it will, and he says these Arabs and Palestinians will have to find a new home because God is bringing His people back to fulfill the covenants He made with Abraham, Isaac, and Jacob.
