She told those
Who had been
About what happened.
They were mourning
ἐκείνη πορευθεῖσα ἀπήγγειλεν τοῖς μετ’ αὐτοῦ γενομένοις πενθοῦσι καὶ κλαίουσιν
This text is similar to Matthew, chapter 28:8, but it was all the women, not Mary Magdalene alone who told them about the resurrection of Jesus there. Luke, chapter 24:10, also had all the women tell the apostles about the resurrection. In John, chapter 20:2, only Mary Magdalene told Peter and the other beloved disciple about Jesus’ resurrection. Here Mark said that Mary Magdalene went (ἐκείνη) and told the people who had been with Jesus (πορευθεῖσα ἀπήγγειλεν τοῖς μετ’ αὐτοῦ) what had happened to him. However, this is the only place where it was mentioned that these disciples of Jesus were mourning and weeping (γενομένοις πενθοῦσι καὶ κλαίουσιν). Mary Magdalene told these disciples who had been upset and maybe discouraged about the death of Jesus. Thus, the resurrection of Jesus became common knowledge to the male disciples of Jesus via these women, in particular Mary Magdalene.
