The Torah, or the Pentateuch, is the central reference of the religious Judaic tradition. It has a range of meanings. It can most specifically mean the first five books of the twenty-four books of the Tanakh.
Aliyah is the word that describes the return of the Jewish People from the exile in the Diaspora back to the Land of Israel. The word Aliyah is derived from the verb "laalot" which means "to go up", or "to ascend" in a positive spiritual sense. A person who makes Aliyah is called an Oleh, meaning "one who goes up".
