Luke 9:34-36

Mace(i) 34 while he was speaking, there came a cloud and over-shadowed them, who were seized with fear, at their vanishing in the cloud, 35 from whence a voice issued out, saying, "this is my beloved son, obey him." 36 and before the sound was gone, Jesus was left alone: this they kept secret, and for some time did not acquaint any one in the least with what they had seen.
