Luke 9:36

The scene ends with Jesus alone the center of the disciples’ attention. The disciples told no one what they had seen because Jesus told them to keep it quiet (Matthew 17:9; Mark 9:9). Luke simply recorded the fact and omitted the discussion about Elijah that followed (Matthew 17:10-13; Mark 9:10-13) thus highlighting Jesus’ authority.

The major emphasis in Luke’s account of the Transfiguration is that the glorious Son of God must suffer.
