Ok kiddo, the words "ibis redibis nunquam per bella peribis" are actually Latin, which is a very old language that people don't use as much anymore. This phrase means "You will go, you will return, never you will perish through wars.”
It means that even though you might have to go away somewhere, you will come back, and even if there are wars, you won't die. So, it's a positive and hopeful message that tells us that even though there might be rough times, things will get better and we will be able to return home safely.
