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 doth Jesus take Peter, and James, and John, and bringeth them up to a high mount by themselves, alone, and he was transfigured before them,
3 and his garments became glittering, white exceedingly, as snow, so as a fuller upon the earth is not able to whiten [them].
4 And there appeared to them Elijah with Moses, and they were talking with Jesus.
5 And Peter answering saith to Jesus, `Rabbi, it is good to us to be here; and we may make three booths, for thee one, and for Moses one, and for Elijah one:'
6 for he was not knowing what he might say, for they were greatly afraid.
