But is this the case?
But let’s assume that it is a word divider. Does this prove that the inscription could not have been faked from Masonic texts? No, it does not.
In the 1870 book Freemasonry in the Holy Land, published in the United States and distributed to Masonic lodges, Robert Morris makes two important statements about the Moabite Stone that directly impact whether a Masonic forger could have placed a word divider in the Bat Creek inscription.
First, the Moabite inscription proved, he said, that “the Semitic alphabet was the Phoenician” due to the strong similarities. (Cyrus Gordon, McCulloch’s predecessor, later identified the Bat Creek alphabet as “Caananite.") Second, he stated that “punctuation was carefully observed in old writings, so far as to separate by marks both words and sentences.” The following image or the Mesha Stele, from his text, demonstrates that the style and shape of the letters, along with word divider marks, were well-known in the 1870s and 1880s and was thus not a twentieth-century discovery.
A reasonably perceptive forger would note that this new discovery superseded the reconstructed paleo-Hebrew of the 1868 engraving. It is a short step from there to adding a word divider and some random Maobite characters to make the forged inscription harmonize more closely with newly-established facts. Given that even Cyrus Gordon found some of the characters on the Bat Creek inscription “problematic” (the first two are uncertain, though to me they look like they were drawn from the Maobite Stone), it is not impossible that a forger used parts of Macoy's paleo-Hebrew drawing with extra characters from the Moabite Stone to compose a hoax text.
Is this conclusive proof that the inscription is forged? No, but it removes one obstacle to declaring it a forgery as it can no longer be asserted that a Victorian forger with access to Masonic texts could not have known to use a word divider.
