A rather lengthy article “Hebraisti in Ancient Texts: Does ἑβραϊστί Ever Mean ‘Aramaic’?” by Randall Buth and Chad Pierce has appeared in the Brill volume, The Language Environment of First Century Judaea, Randall Buth and R Steven Notley edd., (Brill, 2014, ISBN 9789004263406). The article looks at the meanings and claims about the meanings of ἑβραϊστί and associated words. Does it ever mean “Aramaic,” or does it always mean “Hebrew”? What are the facts, what have modern authors said and what did ancient authors think?
