OK, I've got to comment on this one. First, whoever is responsible for the link in the OP (perhaps the entire site?) is a Witness. Quotations from the Bible have "Jehovah" in the NT and "exercise faith," a unique Freddie Franz/NWT rendering.
Second, there was an interesting lawsuit in Israel regarding this artifact. The best summary of it, with implications as to the ossuary's authenticity, is in a 21-page appendix in Pieter van der Horst's 2015 book Saxa judaica loquunter: Lessons from Early Jewish Inscriptions (Brill). The Latin in the title means "Jewish stones speak." Van der Horst is a top-notch Dutch scholar who has no interest in biblical faith or apologetics. The value of his contribution is in exposing how, as revealed through the Israeli court case, many of the claims of inauthenticity "were inspired by the fear of being misrepresented as ‘uncritical’ by colleagues” (p. 87). In other words, bona fide scholars jumped on the bandwagon of calling the artifact a fake because they were afraid of being labeled apologetic believers. Nowhere does van der Horst argue for the ossuary’s authenticity, but he certainly does contend for a truly unprejudiced investigation of it.
