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 who, appearing in glory, spoke of his departure which he was about to accomplish in Jerusalem.
32 But Peter and those with him were oppressed with sleep: but having fully awoke up they saw his glory, and the two men who stood with him.
33 And it came to pass as they departed from him, Peter said to Jesus, Master, it is good for us to be here; and let us make three tabernacles, one for thee, and one for Moses, and one for Elias: not knowing what he said.
34 But as he was saying these things, there came a cloud and overshadowed them, and they feared as they entered into the cloud:
35 and there was a voice out of the cloud saying, *This* is my beloved Son: hear him.
