1 Nephi 17:19

And now it came to pass that I, Nephi, was exceedingly sorrowful

because of the hardness of their hearts;

and now when they saw that I began to be sorrowful

they were glad in their hearts,

insomuch that they did rejoice over me, saying:

for we knew that ye were lacking in judgment;

wherefore, thou canst not accomplish so great a work.

because of the hardness of their hearts;
