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 appeared in glory and spoke about His departure, which He was about to accomplish at Jerusalem.

32 Meanwhile Peter and his companions were overcome by sleep, but when they awoke, they saw Jesus’ glory and the two men standing with Him.

33 As Moses and Elijah were leaving, Peter said to Jesus, “Master, it is good for us to be here. Let us put up three shelters —one for You, one for Moses, and one for Elijah.” (He did not know what he was saying.)

34 While Peter was speaking, a cloud appeared and enveloped them, and they were afraid as they entered the cloud.

35 And a voice came from the cloud, saying, “This is My Son, whom I have chosen. Listen to Him!”
