What does Mark 15:47 mean?

Mary Magdalene and another Mary, the mother of James the less and Joses, were with several other women during the crucifixion. They follow Joseph of Arimathea and Nicodemus (John 19:39) to see where they will place Jesus' body. Although Nicodemus has brought seventy-five pounds of myrrh and aloes (John 19:39), the women intend to return and properly prepare Jesus for burial (Luke 23:56).

It is for this reason Mary Magdalene, the other Mary, Salome (Mark 16:1), and Joanna, with others, return to the tomb after the Sabbath (Luke 24:10). They wonder how they will roll away the stone, and are of course met with an empty tomb and an angel who explains that Jesus has risen from the dead (Mark 16:2–6). The angel tells them to report to the men. They do (Mark 16:6–7; Matthew 28:1–8), and Peter and John run to see the empty tomb (Luke 24:1–12; John 20:2–10). They leave again, but Mary Magdalene returns, distraught that Jesus' body is gone (John 20:11–18). Jesus approaches her, so healed from His ordeal that she doesn't recognize Him.

The first person Jesus will speak to is one of these women, an individual woman from whom Jesus had expelled seven demons (Luke 8:2). Now, however, she and a friend watch as Joseph of Arimathea (Mark 15:46) and Nicodemus (John 19:39) roll the stone on the grave of the one who was supposed to be king.
