In the older Hebrew dictionaries, the Classical Hebrew vocabulary was reckoned at ca. 8,400 different words (lemmas). The discovery in the 20th century of new Classical Hebrew texts has added some ca. 1,400 words to the dictionary, and a proliferation of scholarly proposals to find in our texts Hebrew words not hitherto recognized has produced another ca. 4,000 (though many of these proposals are by no means accepted by all scholars). Classical Hebrew is now attested by ca. 14,000 words or potential words. However, many of these are proper names.
I think the kangaroo is represented by the name Shelah. The joey is the young “sprout” that is born and “sent” to the pouch which is like the hide or “blanket” that is spread out where it has its “meal”.
The verb שלח (shalah) means to send; to send whatever from messengers to arrows. It may even be used to describe a plant’s offshoots or branches.
Noun שלח (shelah) refers to some kind of weapon, apparently a kind of missile. Plural noun שלוחים (shilluhim) means a send-off; a sending away or parting gift. Noun שלוחה (sheluha) refers to a shoot or branch. Noun משלח (mishlah) describes an outstretching of one’s hand (i.e. an undertaking, or referring to the place where the letting go takes place). Noun משלוח (mishloah) also means an outstretching or a sending. Noun משלחת (mishlahat) describes a discharge from service, or a deputation.
The noun שלחן (shulhan) means table. It may actually stem from a whole other but identical verb that originally described the skinning an animal and stretching the hide out to dry. Possibly helped by the previous verb, this outstretching of a hide became attached to the laying down of a blanket (or indeed a hide) in order to stall goods on it (like the elements of a meal). When someone invented a table on legs the word to describe it was lifted from the old custom of picnicking on a blanket: a stretcher-outer.
Using the timeline I have presented in other topics, our common decent with Shelah the son of Arphaxad (or Cainan according the Luke) is approximately 130 mya.
