My father, Enos, asked me to write a few words to keep our genealogy. 
2 And as these plates are small, and as these things are written for the intent of the benefit of our brethren the Lamanites, wherefore, it must needs be that I write a little; but I shall not write the things of my prophesying, nor of my revelations. For what could I write more than my fathers have written? For have not they revealed the plan of salvation? I say unto you, Yea; and this sufficeth me.
I'm writing these small plates for the Lamanites. 
Because the plates are small I won't include my prophecies or revelations. 
3 Behold, it is expedient that much should be done among this people, because of the hardness of their hearts, and the deafness of their ears, and the blindness of their minds, and the stiffness of their necks; nevertheless, God is exceedingly merciful unto them, and has not as yet swept them off from the face of the land.
The Nephites have become blind, deaf, stiff-necked, and hard of heart. God has exceedingly merciful by not killing them all by now. 
4 And there are many among us who have many revelations, for they are not all stiffnecked. And as many as are not stiffnecked and have faith, have communion with the Holy Spirit, which maketh manifest unto the children of men, according to their faith.
But many of us who have had revelations aren't stiff-necked and have had communion with the Holy Spirit. 
5 And now, behold, two hundred years had passed away, and the people of Nephi had waxed strong in the land. They observed to keep the law of Moses and the sabbath day holy unto the Lord. And they profaned not; neither did they blaspheme. And the laws of the land were exceedingly strict.
Two hundred years have passed away , and the Nephites waxed strong. They kept the law of Moses and the sabbath day. They weren't profane, they didn't blaspheme, and their laws were strict.
6 And they were scattered upon much of the face of the land, and the Lamanites also. And they were exceedingly more numerous than were they of the Nephites; and they loved murder and would drink the blood of beasts.
The Lamanites were more numerous than the Nephites.
They loved to murder people and drink the blood of beasts.
7And it came to pass that they came many times against us, the Nephites, to battle. But our kings and our leaders were mighty men in the faith of the Lord; and they taught the people the ways of the Lord; wherefore, we withstood the Lamanites and swept them away out of our lands, and began to fortify our cities, or whatsoever place of our inheritance.
They attacked our cities, but our kings and leaders were mighty men who protected us from their assaults. 
8 And we multiplied exceedingly, and spread upon the face of the land, and became exceedingly rich in gold, and in silver, and in precious things, and in fine workmanship of wood, in buildings, and in machinery, and also in iron and copper, and brass and steel, making all manner of tools of every kind to till the ground, and weapons of war -- yea, the sharp pointed arrow, and the quiver, and the dart, and the javelin, and all preparations for war.
We multiplied and were rich in gold, silver, and precious things. We had buildings, tools, weapons, and machinery made of iron, copper, brass, and steel. 
9 And thus being prepared to meet the Lamanites, they did not prosper against us. But the word of the Lord was verified, which he spake unto our fathers, saying that: Inasmuch as ye will keep my commandments ye shall prosper in the land.
So the Lamanites didn't prevail against us.
10And it came to pass that the prophets of the Lord did threaten the people of Nephi, according to the word of God, that if they did not keep the commandments, but should fall into transgression, they should be destroyed from off the face of the land.
11 Wherefore, the prophets, and the priests, and the teachers, did labor diligently, exhorting with all long-suffering the people to diligence; teaching the law of Moses, and the intent for which it was given; persuading them to look forward unto the Messiah, and believe in him to come as though he already was. And after this manner did they teach them.
But the Lord's prophets threatened the Nephites, saying that if they didn't keep the commandments and look forward to the Messiah as though he was already present, they'd be destroyed.
In this way, the prophets pricked the hearts of the Nephites with the word and caused them to repent.
14 And I, Jarom, do not write more, for the plates are small. But behold, my brethren, ye can go to the other plates of Nephi; for behold, upon them the records of our wars are engraven, according to the writings of the kings, or those which they caused to be written.
Now 238 years have passed  and I have stopped writing because the plates are small.
But you can read more on the plates of Nephi, which records the wars of the kings.
Now I'm delivering these plates to my son, Omni.
