This is not a pdf. However, we can still read to find valuable information. The book is call Lephi in the Desert, The World of the Jaredites by Hugh Nibley. You can order, there are different versions printed so be aware. First edition are usually the best.
The version here isn's the first ed. I assume. It's free so I can't complain. This all I can find.
In part 1, we learned how Lehi is a wealthy merchant, this is confirmed in the Lehi abridgement.
Lehi and the Arabs
Lehi was very rich, and he was a trader, for his wealth was in the form of "all manner of riches" (1 Nephi 3:16) such as had to be brought from many places. His world was a world of travelers and merchants. The princes of the Delta were merchants, 21 the princes of the Syrian and Palestinian cities were also, as the Amarna tablets show, merchants; the story of Wenamon tells us that the princes of Phoenicia and Philistia were merchants; the Arab princes of the desert were merchants; and the merchants of Egypt and Babylonia would meet in their tents to transact business; 22 the two wisest of the Greeks, Lehi's great contemporaries Solon and Thales, both traveled extensively in the East�on business.
