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 And after six days Jesus took with him Peter and James and John, and led them up a high mountain by themselves. And he was transfigured before them,
3 and his clothes became radiant, intensely white, as no one on earth could bleach them.
4 And there appeared to them Elijah with Moses, and they were talking with Jesus.
5 And Peter said to Jesus, "Rabbi, it is good that we are here. Let us make three tents, one for you and one for Moses and one for Elijah."
6 For he did not know what to say, for they were terrified.
