For example, there's a website that has the entire hebrew bible text online [and I assume the original hebrew letters [without translation] is public domain [correct me if I'm wrong]] but the website says at the bottom

all of the rights, in the books' texts, according to how they are published in [the website named] "holy books] belong to [the organization known as] "machon mamray". The material appears on the website "sniut" [the base domain] based on a license from "machon mamray", and by courtesy of it, much of the [content that is] searched in this website is in collaboration with [another company] "moorfeeks"

the point is, they have sme kind of license for all of this text, and it says "all rights reserved", but the original hebrew text itself is [to the best of my knowledge] in the public domain, can I extract only the hebrew text itself and republish it with no issues?
