Mark 8:30-32

Then he warned them not to breathe a word of this to anyone. From then on, Jesus began to tell his disciples that he, the Son of Man, was destined to go to Jerusalem and suffer great injustice from the elders, leading priests, and religious scholars. He also explained that he would be killed and three days later be raised to life again. Jesus opened his heart and spoke freely with his disciples, explaining all these things to them. Then Peter took him aside and rebuked him.
