While I welcome early evidence of Israel's occupation of Palestine and the use of the tetragrammaton, I think some caution should be exercised in accepting this report at face value. "Dr" Stripling, who directed the excavations, has no archaeological qualifications and the Associates for Biblical Research is a "christian apologetics ministry" so there may be some wishful thinking in the report.
Essentially, we should wait for the "peer-reviewed paper presenting all the details" before reaching any conclusions, but even so, some claims are extraordinary. One of the epigraphers who studied the amulet noted that "the quality of the inscription is extraordinary, and that the person who wrote it would have been perfectly capable of writing the entire Pentateuch". They claim to have identified 40 letters on the inside of the amulet which include the word "curse" or "accursed" 10 times. That makes up 30 of the 40 letters. The remaining letters are used to write "God", "die" and "YHW". The Pentateuch is made up of 8,500+ words so the ability to write four words indicates some literacy but hardly qualifies them to write the Pentateuch.
Apart from this consider what we actually know about the amulet. The amulet was not found in a stratified context and there doesn't seem to be anything other than the writing that can be used to date it. At the presentation there were no images shown of what the writing looked like, only a drawing by Gershon Galil. The writing, described as proto-alphabetic, could be early Hebrew but it could as easily be early Ugaritic, Phoenician, Aramaic, Akkadian or any Semitic language. It is possible the claims of what is written are accurate, but until the images are published and epigraphers have an opportunity to examine them, it will remain the product of wishful thinking of people dependent on the funding they get for their endeavours.
