Genesis (Hebrew: בְּרֵאשִׁית, Greek: Γένεσις, meaning "birth", "creation", "cause", "beginning", "source" or "origin") is the first book of the Torah, the Tanakh, and the Old Testament. In Hebrew, it is called בראשית (B'reshit or Bərêšîth), after the first word of the text in Hebrew (meaning "in the beginning"). This is in line with the pattern of naming the other four books of the Pentateuch. As Jewish tradition considers it to have been written by Moses, it is sometimes also called The First Book of Moses.
