Mark 9:30-32 NIV

[30] They left that place and passed through Galilee. Jesus did not want anyone to know where they were, [31] because he was teaching his disciples. He said to them, “The Son of Man is going to be delivered into the hands of men. They will kill him, and after three days he will rise.” [32] But they did not understand what he meant and were afraid to ask him about it.
