1 Nephi 16:20

And it came to pass that Laman and Lemuel and the sons of Ishmael

did begin to murmur exceedingly,

because of their sufferings and afflictions in the wilderness;

and also my father began to murmur against the Lord his God;

yea, and they were all exceedingly sorrowful,

even that they did murmur against the Lord.

yea, and they were all exceedingly sorrowful,
