Allen & David Richardson and Anthony Bentley note that the Book of Mormon was written by prophets who were conversant with Hebrew customs and language (1 Nephi 1:2). This is made evident by the frequent use of an ancient Hebrew literary device known as anaphora. Anaphora is defined as “the repetitions of the same word at the beginning of successive sentences.”
An excellent example of anaphora is found in Helaman 13:11-16:
Yea, wo unto this great city of Zarahemla … wo be unto this great city because of the wickedness and abominations which are in her. Yea, and wo be unto the city of Gideon … Yea, and wo be unto all the cities which are in the land round about … because of the wickedness and abominations which are in them.
