A careful reading of these words of Zenos seems to indicate that the ‘three days of darkness’ that were to accompany the crucifixion of Christ were not to be a sign to those of the house of Israel around Jerusalem but only to those who lived away from Jerusalem or on ‘the isles of the sea.’ (1 Nephi 19:10.) The sign to be given to those at Jerusalem is listed later by Zenos wherein he states, ‘And as for those who are at Jerusalem … they shall be scourged by all people, because they crucify the God of Israel.’ (1 Nephi 19:13.)(Daniel H. Ludlow, A Companion to Your Study of the Book of Mormon, p. 120)
