“After six days Jesus took with him Peter, James and John the brother of James, and led them up a high mountain by themselves. There he was transfigured before them. His face shone like the sun, and his clothes became as white as the light. Just then there appeared before them Moses and Elijah, talking with Jesus. Pete said, “Lord, it is good for us to be here. If you wish, I will put up three shelters – one for you, one for Moses and one for Elijah. While he was still speaking, a bright cloud enviroped them, and a voice from the cloud said, ‘This is my son, whom I love, with him I am well pleased. Listen to him!’ “(Matthew 17:1-5)
The bright cloud overshadowed the Lord on the mount of Tranfiguration; and as with the children of Israel in the wilderness, God spoke to the disciples out of the cloud. We read in 1 corinthians 10:1-2, that all the children of Israel “were under the cloud, and all passed through the sea, and were all baptized unto Moses in the cloud and the sea.” This seems to indicate that the cloud was a type of the Holy Spirit. The cloud was seen again when the Lord Jesus ascended. For while the disciples were gathered around him on the mount of Olives, “He was taken up and a cloud received him out of their sight” (Acts 1:9).
