I recall this as being one of Freddie's concepts.
Whether it existed as a belief before Freddie's time, i.e. in Charlie Russels time, is something I'm not sure about, but clearly it fits in with the mythology of the Bible Students.
It is, as an idea, totally dependent on the witness/biblical myth**, a myth that is undermined by the archeology of human migrations across the globe, and the modern study of languages.
I have neither the inclination nor the time to do a more complete study on the topic, but by using google scholar, it is possible to locate some scholarly studies on the origins of the Hebrew language.
I've found:

Oneeyedjoe's post does not state whether the speaker differentiated between modern Hebrew and ancient Hebrew. There is a difference. This book may help us to understand the difference

Is Biblical Hebrew a language?
Edward Ullendorff
ABSTRACT:
There is no need to explain what I mean by “Biblical Hebrew” (BH): I refer, of course, to the language of the major part of the Old Testament (OT) which is written in a Canaanite tongue clearly distinguished from the few chapters in Daniel and Ezra which are composed, or at any rate extant, in Aramaic. While we have no knowledge of the precise nature of the language spoken by the Hebrew immigrants into Canaan, it is likely that from a linguistic point of view the OT owes more to the vanquished Canaanites than to the conquering Hebrews. The latter are called 'iḇrīm already in the Patriarchal narratives (Gen. xiv, 13, xl, 15, etc.), but their language ('iḇrīṯ) is never as such mentioned in the OT. This may, of course, be owing to one of those purely fortuitous circumstances in the transmission of the ancient Hebrew vocabulary with which this paper is in part concerned. Whether yәhūḏīṯ‘Jewish’ (2 Kings xviii, 26, Isa. xxxvi, 11, etc.), śәṗaṯ kәna'an ‘the language of Canaaan’ (Isa. xix, 18), and 'iḇrīṯ‘Hebrew’ (first attested in the prologue to Ben Sira) are wholly identical is—as I have endeavoured to show elsewhere—not fully established.

** Grin-I'm referring to the myth that Yahweh created the first humans some 5000 odd years ago, and despite the disobedience of Adam and Eve, some humans 'walked with God,' perhaps literally (another grin) and those humans evolved into the glorious nation of Israel (when obedient to Yahweh) and to a train-wreck when disobedient.
