Isaiah 14:6 (King James Bible) he that ruled the nations in anger is persecuted and none hindereth
The 1849 LDS edition replaced the past-tense ruled with the present-tense ruleth, probably in anticipation of the present-tense hindereth in the following clause. The 1920 LDS edition restored the original ruled, which is also the King James reading.
Summary: Maintain the past-tense ruled in 2 Nephi 24:6, the earliest extant reading as well as the King James reading.
