Hebrew.
Although, it is important to note that the term "official language" refers to a national government, which Judaism does not have. While Israel is a Jewish country, it is not a country ruled by Judaism. (This is as opposed to Vatican City which is a nation ruled by Catholicism.) Judaism does have a sacred language and a religious language (both of which are Hebrew), but the term "official language" is not apropos.
