"Tanach" is a contraction for "Torah, Neviim, Kesuvim" - the three parts of the Bible (or as the Christians call it, the Old Testament). The first part, the Torah, contains the five books of Moses; the second part contains books written by the Prophets ("Neviim" in Hebrew); and the third part contains the remaining books ("Kesuvim" - "Writings"). The order of the books in Neviim and Kesuvim may be different in some Christian editions of the Old Testament than it is in the Jewish version, and some Christian Bibles contain additional books (the "Apocrypha"); but all the books of the Jewish Bible are in all the versions of the Christian Old Testament. They should correspond verse by verse, but of course there
will be differences in wording between one translation and another. The Jewish translations are likely to be more accurate because they are based on the original Hebrew.
