Scriptural: Benjamin concludes this part of his discourse with a summary of his reason for teaching language and the brass plates to his sons (Mormon's interjection in the next verse makes it clear that this is not the last of Benjamin's teachings). The reason for learning to read the brass plates is directly related to the keeping of the commandments, and those are directly related to the promise from the Lord to the Nephites, that this land would be theirs and they would prosper if they did keep those commandments (1 Nephi 4:14, 2 Nephi 1:20).
