Here the 1874 RLDS edition omitted the indirect object Shared. Interestingly, the expression “give battle” always has an indirect object, represented below as X, in the Book of Mormon text, but it occurs in three different forms (in the following I provide one example of each type):
The original manuscript is not fully extant here in Ether 13:30, but spacing between extant fragments argues that Shared was in 𝓞. The critical text will maintain the earliest reading, “and Coriantumr gave Shared battle again”.
Summary: Maintain in Ether 13:30 the indirect object Shared, which is found in 𝓟 and was presumably in 𝓞.
