Here ends the saga of the plates. Nephi begins the story as a young man, and ends the story as one of the principle characters of his families exodus. He starts as a precocious child, and ends the episode a budding prophet in his own right. Note that it was not only Lehi who searched the brass plates. Nephi himself is involved in understanding the import of the records which he gave so much to obtain (v.21 "we had obtained the records... and searched them...).
