Something about his father's vision struck Nephi more strongly than any other vision his father had received. Nephi did not ponder the vision which led them from Jerusalem - he believed. Nephi did not request of God a replay of the vision which sent the brothers back to Jerusalem for the brass plates. Nephi knew that they Lord would provide a way. Nevertheless, this vision impresses him tremendously. The reason for that impression is not in the symbology which Nephi has already described, but in the ultimate meaning of those symbols, the meaning of which is the part of the vision which so intrigued him that he would ponder it.
