1 Nephi 18:17

Now my father, Lehi, had said many things unto them,

and also unto the sons of Ishmael;

but, behold, they did breathe out much threatenings

against anyone that should speak for me;

and my parents being stricken in years,

and having suffered much grief because of their children,

they were brought down, yea, even upon their sick-beds.

and also unto the sons of Ishmael;
