ANSWER: There is no discrepancy here, nor in the number of Marys at the tomb — two being mentioned by Matthew, Mark and Luke, while John speaks of Mary Magdalene alone. Similar instances are the demoniacs of Gadara, and the blind men at Jericho; where, in both cases, Matthew speaks of two persons, but Mark and Luke mention only one. Something peculiar in one rendered him more prominent than the other. When Lafayette revisited America in 1824, he was everywhere received with joy and much was said about him in the daily papers; some of which did not mention his son, who was with him, eclipsed not by the shadow of his father, but by his glory as a Major General in Washington's army. This is the sound rule of interpretation in such cases: "He who speaks of the larger number includes the smaller; he who mentions the smaller does not deny the larger."
