The 1841 LDS British edition accidentally dropped the definite article the from the phrase “to the dust”. This the was restored in the second printing of the 1852 edition, probably by reference to the 1840 edition. Elsewhere the text has 34 occurrences of “the dust”. The only occurrence of dust without the is in 2 Nephi 15:24, an Isaiah quotation (“and their blossom shall go up as dust”).
Summary: Maintain the definite article for “the dust” in 1 Nephi 22:14.
