Omni 1:11 - 1:15

Omni 1:11 And behold, the record of this people is engraven upon plates which is had by the kings, according to the generations; and I know of no revelation save that which has been written, neither prophecy; wherefore, that which is sufficient is written. And I make an end.

A more complete account of the history of these events are on the other plates. He says he knows of no new revelations or prophecies other than what is in their scriptures. And since these plates are only for recording spiritual events, he finishes his contribution to the record.
[Great example of what happens when there is no revelation or prophets among the people. It is continuous warfare without them. That we see in our world today.]

Omni 1:12 Behold, I am Amaleki, the son of Abinadom. Behold, I will speak unto you somewhat concerning Mosiah, who was made king over the land of Zarahemla; for behold, he being warned of the Lord that he should flee out of the land of Nephi, and as many as would hearken unto the voice of the Lord should also depart out of the land with him, into the wilderness—

Amaleki is the next record keeper. He is the son of Abinadom. Amaleki is going to relate to us an account of a man named Mosiah. He was the king of a land called Zarahemla which was not the land of his nativity. Mosiah was warned to leave the land of Nephi and depart into the wilderness with all those righteous that would follow him.
[Common theme in scripture. When wikcedness get to difficult to live with, the righteous are lead into the wilderness. We see this with Moses and Brigham Young in particular.]

Omni 1:13 And it came to pass that he did according as the Lord had commanded him. And they departed out of the land into the wilderness, as many as would hearken unto the voice of the Lord; and they were led by many preachings and prophesyings. And they were admonished continually by the word of God; and they were led by the power of his arm, through the wilderness until they came down into the land which is called the land of Zarahemla.

This king Mosiah took as many as would go with him and departed into the wilderness as commanded by the Lord. They were encouraged to leave because of the preaching and prophecies of the prophets among them. And it was these prophets that kept encouraging them to remain faithful in spite of the difficulty of the trip so they would have the Lord’s guidance. Eventually they arrived at a place that was called Zarahemla.
[Wonder if Mosiah knew where they were going or not. Was Zarahemla known to them or just to him and that’s why they were heading that way or was it a surprise to see the place and the people when they arrived?]

Omni 1:14 And they discovered a people, who were called the people of Zarahemla. Now, there was great rejoicing among the people of Zarahemla; and also Zarahemla did rejoice exceedingly, because the Lord had sent the people of Mosiah with the plates of brass which contained the record of the Jews.

The people of Zarahemla and their leader who was named Zarahemla were happy to see the Nephites when they arrived in their country. They were especially glad to see the brass plates containing the scriptures because they brought no records with them.

Omni 1:15 Behold, it came to pass that Mosiah discovered that the people of Zarahemla came out from Jerusalem at the time that Zedekiah, king of Judah, was carried away captive into Babylon.

Mosiah and his people learn that the ancestors of the people of Zarahemla came from Jerusalem just after Lehi had. Their departure coincided with the capture of king Zedekiah and his removal to Babylon as a prisoner of the Babylonians.
[As we will learn, these people had saved one of Zedekiah’s sons and had fled Jerusalem. Not sure if this son was missed by the Babylonians as the account says they were all killed in front of Zedekiah. It may have been the aim of these people to reestablish the Jews in another place using this son as the center around which to rebuild Judah. In any case, Zedekiah must have known that not all of his sons were killed. I would imagine that he was happy to know that at least one of his sons escaped.]
