While copying from π to π, Oliver Cowdery accidentally replaced the singular murmuring with the plural murmurings. This error may have been inο¬uenced by the immediately preceding plural form journeyings. The plural noun form journeyings itself is undoubtedly correct; the text prefers the plural journeyings over the singular noun journeying ( 7 to 1).
Elsewhere the text has a variety of examples with the gerundive verbal following the preposition without:
Thus in 1 Nephi 17:2, the singular murmuring in π should be accepted as a gerundive verbal since it is preceded by without. On the other hand, the count noun murmuring(s) is always in the plural; for discussion, see 1 Nephi 16:25.
Summary: Restore the gerundive murmuring in 1 Nephi 17:2; the gerundive verbal is perfectly acceptable after the preposition without.
