18Once when Jesus was praying by himself and his disciples were nearby, he asked them, “Who do the crowds say that I am?” 19They answered, “John the Baptist; others say Elijah; and still others that one of the prophets of long ago has risen.” 20Then he said to them, “But who do you say that I am?” Peter answered, “The Christ of God.” 21But he forcefully commanded them not to tell this to anyone, 22saying, “The Son of Man must suffer many things and be rejected by the elders, chief priests, and experts in the law, and be killed, and on the third day be raised.”
