Amaleki was the last in a line of record-keepers extending from the time of Jacob down to the time of King Benjamin. Presumably, Amaleki traveled with Mosiah and brought with him the small plates of Nephi on which he recorded his brief account, comprising only nineteen verses of the Book of Mormon. Having no posterity, Amaleki delivered the plates to King Benjamin and added his testimony of the gospel.
Knowing king Benjamin to be a just man before the Lord, wherefore, I shall deliver up these plates unto him, exhorting all men to come unto God, the Holy One of Israel, and believe in prophesying, and in revelations, and in the ministering of angels, and in the gift of speaking with tongues, and in the gift of interpreting languages, and in all things which are good; for there is nothing which is good save it comes from the Lord; and that which is evil cometh from the devil.
And now, my beloved brethren, I would that ye should come unto Christ, who is the Holy One of Israel, and partake of his salvation, and the power of his redemption. Yea, come unto him, and offer your whole souls as an offering unto him, and continue in fasting and praying, and endure to the end; and as the Lord liveth ye will be saved.
