In 1 Nephi 16, Lehi's family begins their journey. The Lord provide a ball that gives them the direction that they should take. The Lord also writes things on the Liahona to give them understanding. This writings changed from time to time according to their faith and diligence.
In chapter 17, Nephi remarks that they didn't use much fire (v.12) and then says
;"for [the Lord] said: I will make thy food become sweet, that ye acook it not;",... I find it interesting that Nephi is quoting from somewhere and using these quotes to teach his brethren (v. 15). I wonder if these might have been sayings on the Liahona.
Nephi quotes the Lord in the next verse: "And I will also be your light in the wilderness; and I will prepare the way before you, if it so be that ye shall keep my commandments; wherefore, inasmuch as ye shall keep my commandments ye shall be led towards the promised land; and ye shall know that it is by me that ye are led."
Nephi quotes the Lord again in verse 14: "Yea, and the Lord said also that: After ye have arrived in the promised land, ye shall know that I, the Lord, am God; and that I, the Lord, did deliver you from destruction; yea, that I did bring you out of the land of Jerusalem."
Perhaps, Nephi is getting these quotes from the brass plates or from his or his father's revelations. Of course, I don't know, but could it be possible the he is quoting directly from what was written on the Liahona? The writings are very specific to their travels in the wilderness. He seems to be reminding he brethren of the something they would recognize that it came from a legitimate source. The Liahona could have been the source.
