The words “And it came to pass” appear more than 1,400 times in the Book of Mormon. On the average, that’s more than 2.63 times per page, or about 20% of the verses. Mark Twain commented about this excess:
“‘And it came to pass’ was his pet. If he had left that out, his Bible would have been only a pamphlet.”
Mark Twain, Roughing It (Hartford, CT: American Publishing Co., 1891), 127-128.
