The Celtic languages are part of the Indo-European Family as are the Germanic, Latin, Slavic and Indo-Iranian languages. Hebrew is part of the Afro-Asiatic Family. There is no relationship whatsoever.

There is no reason to expect The Lost Tribes of Israel carried the Hebrew language intact past their Assyrian Captivity since they lost virtually all their identity as Israelites prior to their exodus and subsequent diaspora.  That is what their punishment was all about.

(This, despite the impressive documentation by E. Raymond Capt in his outstanding book Assyrian Tablets in the British Museum which shows the extensive Hebrew roots in todays Germanic languages.)

I'm not at all convinced the Celts are the Lost Tribes, but I find the theory fascinating and I keep an open mind. However, when studying Beowulf last year, I was surprised to see that some of the rhyming patterns were similar to what I've been told characterizes Hebrew.
