Luke 9:18-21

One time when Jesus was off praying by himself, his disciples nearby, he asked them, “What are the crowds saying about me, about who I am?” They said, “John the Baptizer. Others say Elijah. Still others say that one of the prophets from long ago has come back.” He then asked, “And you—what are you saying about me? Who am I?” Peter answered, “The Messiah of God.” Jesus then warned them to keep it quiet. They were to tell no one what Peter had said.
