In light of the result of the famous trial of Oded Golan, Robert Deutsch, etc., and the enormous amount of discussions about these results, once again the question of the authenticity of the Jehoash Inscription has been repeatedly discussed. Putting aside the question of the physical examination of the object, a new article by my colleague Ed Greenstein quite clearly demonstrates that from an analysis of the language of the inscription it is quite clearly a modern forgery, in which most of the text is taken from the biblical text, with some additions from some other, bona fide inscriptions, along with several misuses of biblical Hebrew terms according to modern Hebrew usages.
He quite clearly takes apart V. Sasson’s and C. Cohen’s claims that linguistically it is ancient.
