Luke 9:34 Meaning and Commentary

Luke 9:34

While he thus spake there came a cloud
While Peter was making the above request, before an answer was returned, a cloud appeared, a very uncommon one, as a symbol of the divine presence: "and overshadowed them"; Jesus, Moses, Elias, and the disciples:

and they feared as they entered into the cloud;
either as they themselves entered into it, that coming gradually over them, because of the glory of it, and the solemnity that attended it; or as Moses and Elias entered into it; and so the Syriac and Persic versions read, "they feared when they saw Moses and Elias enter into the cloud"; which took them out of their sight: just as the cloud received Jesus out of the sight of his disciples, when he ascended to heaven, ( Acts 1:9 ) .

Luke 9:34 In-Context

32 Peter and his companions were sound asleep, but they woke up and saw Jesus' glory and the two men who were standing with him.
33 As the men were leaving Jesus, Peter said to him, "Master, how good it is that we are here! We will make three tents, one for you, one for Moses, and one for Elijah." (He did not really know what he was saying.)
34 While he was still speaking, a cloud appeared and covered them with its shadow; and the disciples were afraid as the cloud came over them.
35 A voice said from the cloud, "This is my Son, whom I have chosen - listen to him!"
36 When the voice stopped, there was Jesus all alone. The disciples kept quiet about all this and told no one at that time anything they had seen.
