Mark 9:7-9

Amplified Bible

⁷ Then a cloud formed, overshadowing them, and ^[a]a voice came out of the cloud, “This is My beloved Son. Listen to Him and obey Him!” ⁸ Suddenly they looked around and no longer saw anyone with them, except Jesus alone.

⁹ As they were coming down from the mountain, Jesus expressly ordered them not to tell anyone what they had seen, until the Son of Man had risen from the dead.
