Hebrew is a reconstructed language. Whilst some roots will predate the Torah, most won't.

Several words, like the infamous "shibboleth" won't be inherited, or their meanings may wildly differ.

I mean that it already appears in the Bible, in old Hebrew (which is close to, but isn’t exactly Aramaic), with the meaning “to feed and provide” - and I did not find any documentation about how it formed (or came into) Hebrew.

Which means of course m, that it was already in use before the Bible was canonicalized.
