Luke 9:18-22

18 Once when Jesus was praying alone, with only the disciples near him, he asked them, "Who do the crowds say that I am?"
19 They answered, "John the Baptist; but others, Elijah; and still others, that one of the ancient prophets has arisen."
20 He said to them, "But who do you say that I am?" Peter answered, "The Messiah of God."
21 He sternly ordered and commanded them not to tell anyone,
22 saying, "The Son of Man must undergo great suffering, and be rejected by the elders, chief priests, and scribes, and be killed, and on the third day be raised."
