Enos 1:16 - 1:20

Enos 1:16 And I had faith, and I did cry unto God that he would preserve the records; and he covenanted with me that he would bring them forth unto the Lamanites in his own due time.

Enos desires that the records he and his father and uncle kept would be part of the record to come forth at some future time to the Lamanites when it was opportune for that to happen. The Lord promised him that it would happened as he wished.

Enos 1:17 And I, Enos, knew it would be according to the covenant which he had made; wherefore my soul did rest.

Enos knew that it would happen as the Lord had covenanted with him to do so.

Enos 1:18 And the Lord said unto me: Thy fathers have also required of me this thing; and it shall be done unto them according to their faith; for their faith was like unto thine.

The Lord said that his father and uncle (Nephi) had been promised this same thing. For their fervency was like his own.
[I guess, Enos had not look into the writings of his fathers as he would have known this for himself. I wonder if his ignorance of this was an indication of his lack of commitment up to that point to the Gospel. Being by himself and having a time to reflect caused him to reevaluate his life. His reevaluation caused his changing his behavior and thought processes in relation to his family and his enemies.]

Enos 1:19 And now it came to pass that I, Enos, went about among the people of Nephi, prophesying of things to come, and testifying of the things which I had heard and seen.

Enos then goes home and tells his people of his experience in the wilderness with the Lord. He is especially concentrating on what will happen to the Nephites if they do not shape up their lives before the Lord.

Enos 1:20 And I bear record that the people of Nephi did seek diligently to restore the Lamanites unto the true faith in God. But our labors were vain; their hatred was fixed, and they were led by their evil nature that they became wild, and ferocious, and a blood-thirsty people, full of idolatry and filthiness; feeding upon beasts of prey; dwelling in tents, and wandering about in the wilderness with a short skin girdle about their loins and their heads shaven; and their skill was in the bow, and in the cimeter, and the ax. And many of them did eat nothing save it was raw meat; and they were continually seeking to destroy us.

Enos wants his descendants to know that the Nephites tried, although in vain, to bring the Gospel to the Lamanites. Their seem to be no way their attitudes towards the Nephites would ever change. They were living like savages in the jungle wearing only enough to cover their private parts and getting their food by hunting only. They lived off of wild game and eat their kills raw. Their only skills were with the bow, and various weapons of war. They were not familiar with farming or with construction as they had no permanent buildings or cities preferring to live as nomads in tents and always on the move to follow the moments of game.
[Seems to be an example of reverse cultural evolution. Rather than native people gradually becoming sophisticated and setting down into cities, the Lamanites went from city folk to native life styles. Might be an indication that when the gospel is rejected and, in addition, people rejecting the spirit which is trying to settle them down to a gospel centered life, they spiral down into a primitive life style.]
