Jaredites

• Mosiah 8:7-11

7) And the king said unto him: Being grieved for the afflictions of my people, I caused that forty and three of my people should take a journey into the wilderness, that thereby they might find the land of Zarahemla, that we might appeal unto our brethren to deliver us out of bondage.

8) And they were lost in the wilderness for the space of many days, yet they were diligent, and found not the land of Zarahemla but returned to this land, having traveled in a land among many waters, having discovered a land which was covered with bones of men, and of beasts, and was also covered with ruins of buildings of every kind, having discovered a land which had been peopled with a people who were as numerous as the hosts of Israel.

9) And for a testimony that the things that they had said are true they have brought twenty-four plates which are filled with engravings, and they are of pure gold.

10) And behold, also, they have brought breastplates, which are large, and they are of brass and of copper, and are perfectly sound.

11) And again, they have brought swords, the hilts thereof have perished, and the blades thereof were cankered with rust; and there is no one in the land that is able to interpret the language or the engravings that are on the plates. Therefore I said unto thee: Canst thou translate?

• Mosiah 28:17

Now after Mosiah had finished translating these records, behold, it gave an account of the people who were destroyed, from the time that they were destroyed back to the building of the great tower, at the time the Lord confounded the language of the people and they were scattered abroad upon the face of all the earth, yea, and even from that time back until the creation of Adam.

• Moroni 9:23

And if they perish it will be like unto the Jaredites, because of the wilfulness of their hearts, seeking for blood and revenge.

The best theory I have seen regarding the origin of the Jaredites, is the idea proposed by Jerry D. Grover, Jr. that they came from the Sumerian culture. Hence, their language is expected to be closely related to Sumerian.
