I am reading the Old Testament from beginning to end for the first time, using the New Jewish Publication Society Tanakh:
Unlike their 1917 translation, the new JPS Tanakh was entirely original and not based on any previous Christian translation. It's both relatively easy to read and accurate to the traditional Masoretic text. The Hebrew Bible is coming alive to me in a way I never imagined.
The word Tanakh is derived from the traditional threefold division of the Hebrew Bible, the Torah (law), Nevi'im (prophets), and Kethuvim (writings). In Luke 24:44, Jesus refers to this threefold division of the Hebrew canon.
I am now at the Book of Ezekiel. While the local Chabad rabbi recommended to me the Artscroll translation, which is more expensive, the local Conservative rabbi recommended the NJPS Tanakh. Orthodox rabbis seem to recommend the Artscroll translation more often, though Orthodox rabbis and scholars participated in the NJPS translation.
A significant difference between the Hebrew Tanakh and Christian translations is that the Books of Chronicles are included at the very end, in order to summarize the story of the Hebrew Bible. In Christian versions, people often skip over the Books of Chronicles, thinking that it's just a repeat of the Books of Kings.
