Mark 9:6 YLT

⁴  And there appeared to them Elijah with Moses, and they were talking with Jesus.

⁵  And Peter answering saith to Jesus, 'Rabbi, it is good to us to be here; and we may make three booths, for thee one, and for Moses one, and for Elijah one:'

⁶  for he was not knowing what he might say, for they were greatly afraid.

⁷  And there came a cloud overshadowing them, and there came a voice out of the cloud, saying, 'This is My Son -- the Beloved, hear ye him;'

⁸  and suddenly, having looked around, they saw no one any more, but Jesus only with themselves.
