Farsi (Iranian) is another one that lasted a long time without too many mutations as far as I know. Arabic is divided into "proper, classical" Arabic which is used for religious purpose (and maybe some other "official" things), a bit like Latin in the middle ages; and various mostly unintelligible dialects used day to day. If I remember correctly, modern Hebrew is pretty much the same as old Hebrew, with various additions to fit the current world. It's somewhat artificial in that it wasn't really spoken before, and was the chosen as the official language in the early 20th century. It's like if someone decided nowadays to use Latin as the official language.
