So you have absolutely no evidence to back up your claim then?
Actually it’s you making a claim that there should be other ossuaries with the same inscription. The fact that a thousand or so ossuaries have survived this long is great but it in no way tells us how many there were to start.
I’m saying that there are various ways this can be interpreted but any interpretation has to be based on the culture and theology of the time (hopefully that will be hashed out in the universities). Plain sense readings of ancient scripts from extinct cultures is only one approach to interpretation. From my POV not a very good one.
