And there was a cloud that overshadowed them: and a voice came out of the cloud, saying,
This is my beloved Son:
hear him.

It seems to me that this cloud is the grace of the Holy Spirit. Naturally, a tent gives shelter and overshadows those who are within; the cloud, therefore, serves the purpose of the tents. O Peter, you who want to set up three tents, have regard for the one tent of the Holy Spirit who shelters us equally.
