Alma 47:31 - Alma 47:36
Alma 47: 31 And it came to pass on the morrow he entered the city Nephi with his armies, and took possession of the city.
Amalickiah with all the Lamanite armies at his back enter the capitol city and took control of it.
Alma 47: 32 And now it came to pass that the queen, when she had heard that the king was slain—for Amalickiah had sent an embassy to the queen informing her that the king had been slain by his servants, that he had pursued them with his army, but it was in vain, and they had made their escape—
Amalickiah had previously sent word to the queen of the murder of her husband and the escape of the alleged perpatrators.
Alma 47: 33 Therefore, when the queen had received this message she sent unto Amalickiah, desiring him that he would spare the people of the city; and she also desired him that he should come in unto her; and she also desired him that he should bring witnesses with him to testify concerning the death of the king.
The queen then sent word to Amalickiah not to attack the city, but come to her in peace with witnesses to give testimony as to death of the king.
Alma 47: 34 And it came to pass that Amalickiah took the same servant that slew the king, and all them who were with him, and went in unto the queen, unto the place where she sat; and they all testified unto her that the king was slain by his own servants; and they said also: They have fled; does not this testify against them? And thus they satisfied the queen concerning the death of the king.
Amalickiah then brought the actual murderer along with those that were involved to testify to the queen of the death of the king. They stated that because the servants of the king had ran from the scene, that it was testimony enough that they committed the murder of the king.
Alma 47: 35 And it came to pass that Amalickiah sought the favor of the queen, and took her unto him to wife; and thus by his fraud, and by the assistance of his cunning servants, he obtained the kingdom; yea, he was acknowledged king throughout all the land, among all the people of the Lamanites, who were composed of the Lamanites and the Lemuelites and the Ishmaelites, and all the dissenters of the Nephites, from the reign of Nephi down to the present time.
Amalickiah then sought favor of the queen and soon married her which made him king of all the Lamanites which included Lamanites, Lemuelites, Ishmaelites, and all the various dissenters of the Nephites living among the Lamanites.
Alma 47: 36 Now these dissenters, having the same instruction and the same information of the Nephites, yea, having been instructed in the same knowledge of the Lord, nevertheless, it is strange to relate, not long after their dissensions they became more hardened and impenitent, and more wild, wicked and ferocious than the Lamanites—drinking in with the traditions of the Lamanites; giving way to indolence, and all manner of lasciviousness; yea, entirely forgetting the Lord their God.
A note about the dissenters. They had had the same instructions about the gospel as the Nephites but since they had left the Nephites and had come to live with the Lamanites, they had become more evil and corrupt than the Lamanites themselves. They not only became like Lamanites in attitude and custom, but they were more wild and ferocious than the Lamanites. They had lost their conscientiousness and engaged in any manner of evil without worrying about the consequences.
