In his treatise on the priesthood before the hard-hearted leaders and citizens of the city of Ammonihah around 82 BC, Alma provided new insights concerning the ancient king and priesthood leader to whom Abraham paid tithes :
Now this Melchizedek was a king over the land of Salem; and his people had waxed strong in iniquity and abomination; yea, they had all gone astray; they were full of all manner of wickedness;
But Melchizedek having exercised mighty faith, and received the office of the high priesthood according to the holy order of God, did preach repentance unto his people. And behold, they did repent; and Melchizedek did establish peace in the land in his days; therefore he was called the prince of peace, for he was the king of Salem; and he did reign under his father.
Now, there were many before him, and also there were many afterwards, but none were greater; therefore, of him they have more particularly made mention.
