Luke 9:36

And when the voice came, Jesus was found alone. And they held their peace, and told no man in those days any of the things which they had seen.

When the voice came ... may be rendered, "When the voice was past," thus associating the words "hear ye him" with the disappearance of Moses and Elijah, and having the necessary implication of "hear Jesus only."

And told no man ... In this the apostles were obedient to the instructions of the Lord (Matthew 17:9), the same reasons why they were not to publish this, at that time, prevailing, as in the instance of Peter's confession of Jesus as the Christ of God (see under Luke 9:21).
