Exegesis:

ekeinē ‘that one,’ i.e. ‘she’: the demonstrative pronoun is used here and in vv. 11, 13, 20, in a way different from that in which it is used in Mark, who never uses it to refer to the disciples.

poreutheisa (vv. 12, 15) ‘going,’ ‘proceeding’: this verb is not used by Mark.

apēggeilen tois met’ autou genomenois ‘she announced (it) to those who had been with him.’ For the verb apaggellō cf. Mk. 5.14.

hoi met’ autou genomenoi ‘those who had been with him’: this description of the disciples, which is not used by Mark, is translated by Arndt & Gingrich ‘his intimate friends’; Goodspeed translates ‘his old companions.’

penthousi kai klaiousin ‘while they were mourning and weeping’: the two present participles describe the state the disciples were in.

pentheō (not in Mark) ‘be sad,’ ‘grieve,’ ‘mourn.’

klaiō (cf. Mk. 5.38) ‘cry,’ ‘weep.’

Translation:

Told requires in some receptor languages not only an object specifying what was said, but also an object indicating who was addressed, e.g. ‘told those who had been with him what had happened,’ or ‘told the news to those who had been with him.’ On the other hand, it is often possible to choose a verb of speaking which requires only an indication of those spoken to, e.g. ‘spoke to those who had been with him.’
