Matthew 17:9

“And as they came down from the mountain, etc.] Where all these things had been transacted, Jesus charged them, saying, tell the vision to no man: by the “vision” is meant, as it is explained in Mark, “what things they had seen”; as Moses and Elias, and the bright cloud that overshadowed them, and Christ transfigured before them, in a surprising, glorious manner.

Matthew 17:10”

“17:9 Jesus could not be fully understood until all of his work was accomplished, particularly his death and resurrection.”
