In the beginning of the record of Zeniff he said that when he found the land of Nephi and observed the Laminates, he saw good among them(Mosiah 9:1). His original intent was to use force to kick them out but after what he saw he changed his mind. He figured they could be reasoned with. In these verses in Jacob we find out what that good was. They kept the commandment to have only one wife and no concubines or prostitutes. The Nephites, on the other hand, were not keeping this commandment and Jacob had to give them verbal cracks for this sin. But even more than that the Lamanites had loving families. Verse 7 tells us that husbands loved their wives, wives loved their husbands and together they loved their children. And before that in verse 6 we are told that because of their obedience to this one commandment that the Lord would bless them and preserve them. That’s how important families are. My question now is, is that why the Lamanites were always so much more numerous than the Nephites? The Nephites are always outnumbered by Laminates and even Mulekites. Who knows…
