Mark 9:4 Meaning and Commentary

Mark 9:4

And there appeared unto them Elias with Moses
Or Moses and Elias, as all the Oriental versions read, as in Mt. 17:3, (See Gill on Matthew 17:3):

and they were talking with Jesus;
concerning his decease, and what he was to do and suffer at Jerusalem, and of which he himself had lately talked with his disciples; so that this might have been a confirmation of these things to them; (See Gill on Matthew 17:3).

Mark 9:4 In-Context

2 Six days later Jesus took with him Peter, James, and John, and led them up a high mountain, where they were alone. As they looked on, a change came over Jesus,
3 and his clothes became shining white - whiter than anyone in the world could wash them.
4 Then the three disciples saw Elijah and Moses talking with Jesus.
5 Peter spoke up and said to Jesus, "Teacher, how good it is that we are here! We will make three tents, one for you, one for Moses, and one for Elijah."
6 He and the others were so frightened that he did not know what to say.
