Isaiah 10:14 (King James Bible) and as one gathereth eggs that are left have I gathered all the earth
The 1953 RLDS edition accidentally replaced gathereth with gathered, probably under the influence of the past participle gathered in the following main clause. The King James Bible has presenttense finite verb forms throughout this sentence (gathereth, are, and have).
Summary: Maintain in 2 Nephi 20:14 the present-tense gathereth, the King James reading.
