Here the 1840 edition replaced the past-tense caused with the present-tense cause, perhaps under the influence of the preceding present-tense verb phrase are engraven. This change was probably unintentional, although one can make sense out of the present-tense usage: a Nephite king would have been ruling when Jarom wrote this passage, and therefore it would not be inaccurate to say that the kings were still having their writings engraven upon the large plates of Nephi. The 1858 Wright edition maintained the present-tense cause, but the past-tense caused was restored in the 1874 RLDS edition. Similar passages in the text use the past-tense or past-participial caused in the phrase “caused to be written”:
