Alma 28

 
1 And now it came to pass that after the people of Ammon were established in the land of Jershon, and a church also established in the land of Jershon, and the armies of the Nephites were set round about the land of Jershon, yea, in all the borders round about the land of Zarahemla; behold the armies of the Lamanites had followed their brethren into the wilderness.

2 And thus there was a tremendous battle; yea, even such an one as never had been known among all the people in the land from the time Lehi left Jerusalem; yea, and tens of thousands of the Lamanites were slain and scattered abroad.
2
3 Yea, and also there was a tremendous slaughter among the people of Nephi; nevertheless, the Lamanites were driven and scattered, and the people of Nephi returned again to their land.

Compare verse 3 with "there was a tremendous slaughter among the people of Nephi" to 1 Samuel 4:17 "there hath been also a great slaughter among the people". Note that of the 15 instances of "great slaughter" in the KJV bible, only the verse in 1 Samuel 4 also mentions the slaughter happening among a people.

4 And now this was a time that there was a great mourning and lamentation heard throughout all the land, among all the people of Nephi--
4
5 Yea, the cry of widows mourning for their husbands, and also of fathers mourning for their sons, and the daughter for the brother, yea, the brother for the father; and thus the cry of mourning was heard among all of them, mourning for their kindred who had been slain.

6 And now surely this was a sorrowful day; yea, a time of solemnity, and a time of much fasting and prayer.

7 And thus endeth the fifteenth year of the reign of the judges over the people of Nephi;

8 And this is the account of Ammon and his brethren, their journeyings in the land of Nephi, their sufferings in the land, their sorrows, and their afflictions, and their incomprehensible joy, and the reception and safety of the brethren in the land of Jershon. And now may the Lord, the Redeemer of all men, bless their souls forever.

9 And this is the account of the wars and contentions among the Nephites, and also the wars between the Nephites and the Lamanites; and the fifteenth year of the reign of the judges is ended.

10 And from the first year to the fifteenth has brought to pass the destruction of many thousand lives; yea, it has brought to pass an awful scene of bloodshed.
10
11 And the bodies of many thousands are laid low in the earth, while the bodies of many thousands are moldering in heaps upon the face of the earth; yea, and many thousands are mourning for the loss of their kindred, because they have reason to fear, according to the promises of the Lord, that they are consigned to a state of endless wo.
Endless/Eternal Punishment

According to D&C 19:6-12 the words “endless” and “eternal” do not mean without end when it comes to “endless torment” or “eternal damnation”. These verses in the D&C explain that these words are used because, “it is more express than other scriptures, that it might work upon the hearts of the children of men.” When people read these words in the Book of Mormon, how do they likely understand the words “endless” and “eternal”? Is this honest communication if D&C 19 reveals the actual meaning of these words?

12 While many thousands of others truly mourn for the loss of their kindred, yet they rejoice and exult in the hope, and even know, according to the promises of the Lord, that they are raised to dwell at the right hand of God, in a state of never-ending happiness.

13 And thus we see how great the inequality of man is because of sin and transgression, and the power of the devil, which comes by the cunning plans which he hath devised to ensnare the hearts of men.

Compare how verse 13 speaks about the devil and that "he hath devised to ensnare" to both 1 Timothy 3:7 and 2 Timothy 2:26 with "the snare of the devil". Note that these are the only two verses in the KJV bible that contain a combination of both "snare" and "devil" (see snare+devil).

14 And thus we see the great call of diligence of men to labor in the vineyards of the Lord; and thus we see the great reason of sorrow, and also of rejoicing--sorrow because of death and destruction among men, and joy because of the light of Christ unto life.
