Jerusalem to the Red Sea
1 Nephi 3:1-10. The Journey Back to Jerusalem The distance from Jerusalem to the Red Sea (the Gulf of Aqaba) is about 180 miles through hot, barren country infested anciently by many marauders. Lehi and his family traveled three days" journey beyond this point (see 1 Nephi 2:5-6). This meant at least a twelve-to-fourteen-day trip one way, which gives added meaning to Nephi's response in 1 Nephi 3:7.
