What king was able to interpret the Jaredite plates?
King Benjamin
1830 version
King Mosiah
Current version
And now Limhi was again filled with joy in learning from the mouth of Ammon that king Mosiah had a gift from God, whereby he could interpret such engravings; yea, and Ammon also did rejoice. Mosiah 21:28
Since King Benjamin was dead at the time, the LDS church changed "king Benjamin" to "king Mosiah" to avoid the obvious error.
