Luke 9:33

Luke 9:33 Meaning and Commentary

Luke 9:33

And it came to pass, as they departed from him
That is, as Moses and Elias departed from Christ; or "when they began to depart", as the Syriac version renders it; or "would depart", as the Arabic and Persic versions; seemed desirous of going, or made some signal or other by which the disciples perceived they were about to go; for, as yet, they were not gone;

Peter said unto Jesus, master, it is good for us to be here, let us
make three tabernacles, one for thee, and one for Moses, and one for
Elias; (See Gill on Matthew 17:4)

not knowing what he said,
nor "what to say", as Mark observes, being in a surprise, and not in a situation to consider and weigh things well, whether what he said was right and proper, or not; (See Gill on Matthew 17:4)

Luke 9:33 In-Context

31 They were glorious to see. And they were speaking about his exodus from this world, which was about to be fulfilled in Jerusalem.

32 Peter and the others had fallen asleep. When they woke up, they saw Jesus’ glory and the two men standing with him.

33 As Moses and Elijah were starting to leave, Peter, not even knowing what he was saying, blurted out, “Master, it’s wonderful for us to be here! Let’s make three shelters as memorials —one for you, one for Moses, and one for Elijah.”

34 But even as he was saying this, a cloud overshadowed them, and terror gripped them as the cloud covered them.

35 Then a voice from the cloud said, “This is my Son, my Chosen One. Listen to him.”
