Here the 1830 edition omitted the phrase “the city of ”. One might consider the omission as possibly intentional since the original text is redundant (“they built a city which they called the city of Helam”). Nonetheless, the 1837 edition restored the original “the city of ”, undoubtedly by reference to the printer’s manuscript.
Usually the text does not show this kind of redundancy; normally we have nonrepetitious language, as in the following sampling involving the words city, land, and valley:
But there are a few more instances in the text of the redundant usage:
None of these examples were removed in the 1830 edition, which argues that the 1830 omission of “the city of ” in Mosiah 23:20 was unintentional. The critical text will retain this kind of redundant usage wherever it is supported by the earliest textual sources.
Summary: Maintain in Mosiah 23:20 the original redundancy in “they built a city which they called the city of Helam”.
