"And it came to pass that he spake unto me saying: Behold I have dreamed a dream, in the which the lord hath commanded me that thou and thy brethren shall return to Jerusalem."
Lehi, the prophet for his family at this time, receives a dream in which he is told that Nephi and his three brothers needed to return to Jerusalem. This is quite an undertaking as they did travel three days with all the provisions they needed.
This would be also harder as great temptations were still in Jerusalem and Nephi and his brothers would have to be very strong in their faith and such to keep on the path of righteousness.
Lehi, himself prophet for family, dream has. Lord inform Lehi, happen Nephi three brother need #back Jerusalem. This hard, why? travel three day have all need.
Hard also why? tempt at Jerusalem, Nephi and brothers need strong faith, focus path right.
