The phrase "Book of Numbers" is commonly used to refer to the fourth book of the Hebrew Bible, which tells the story of the Israelites' journey from Sinai to the Promised Land. However, there are several synonyms for this phrase that can be used to refer to this book. "Bamidbar" is the Hebrew word for "in the desert," which is an appropriate title for this book given the Israelites' travels. "The Book of the Wilderness" is another fitting synonym, as it emphasizes the importance of the desert setting in which much of the action takes place. Additionally, "Numbers" can simply be shortened to "Num" as a synonym for the Book of Numbers.
