"OT" is by far the most annoying, but the most natural to adherents of the "NT". I tend to have small warning bells go off, whenever I see/hear the term "Hebrew X", where X is anything but the Hebrew language itself. The same hold for terms such as "Israelites", because most often I see these in a context to try and differentiate or separate the "Hebrews", "Israelites" or whatever you call the "proto-Jews" and the present day Jews. It is quite likely that I am overly defensive or sensitive to these issues. Because most people are not familiar with the term Tanakh, I often say "Jewish Bible", but from my POV, that is somewhat redundant. ;-)

I doubt this thread has [many] other readers, long as it's been going on. :-)
