1 Nephi 8:1
1 And it came to pass that we had gathered together all manner of seeds of every kind, both of grain of every kind, and also of the seeds of fruit of every kind.
Nephi had not mentioned seeds before this time, and they may not have brought them when they left Jerusalem. If they did not, this may be evidence of other times when the boys left camp. We can be sure that they did not go out into the wilderness to find their seeds, because the seeds he describes are all of domestic plants—the kind that one would find on a well-stocked landed estate. It is possible that they returned, secretly, to their own country estate where they could obtain all the provisions—including seeds—that they needed, without foraging into the countryside and taking anything that did not belong to them.
There is another implication here: sacks of seeds are heavy. This is one more evidence that they had camels. The seeds, tents, and people all suggest we are seeing a large and well equipped caravan. That would have required camel drivers and probably an armed escort made up of Lehi and Ishmael’s servants. Nephi mentions none of these, being concerned that we know only of the leaders of the party. They did no hide without making a fire until the last leg of their journey.
