Luke 9:18–22 (ESV)
18 Now it happened that as he was praying alone, the disciples were with him. And he asked them, “Who do the crowds say that I am?” 19 And they answered, “John the Baptist. But others say, Elijah, and others, that one of the prophets of old has risen.” 20 Then he said to them, “But who do you say that I am?” And Peter answered, “The Christ of God.” 21 And he strictly charged and commanded them to tell this to no one, 22 saying, “The Son of Man must suffer many things and be rejected by the elders and chief priests and scribes, and be killed, and on the third day be raised.”
