Jesus Christ spoke of his death long before it happened. He knew that he would be killed by the evil Jewish leaders, so he prepared the minds of his followers as best he could for the difficult times ahead of them.
He then began to teach them that the Son of Man must suffer many things and be rejected by the elders, chief priests and teachers of the law, and that he must be killed and after three days rise again. Mark 8.31
He was teaching his disciples. He said to them, “The Son of Man is going to be betrayed into the hands of men. They will kill him, and after three days he will rise.” Mark 9.31
They were on their way up to Jerusalem, with Jesus leading the way, and the disciples were astonished, while those who followed were afraid. Again he took the Twelve aside and told them what was going to happen to him. “We are going up to Jerusalem,” he said, “and the Son of Man will be betrayed to the chief priests and teachers of the law. They will condemn him to death and will hand him over to the Gentiles, who will mock him and spit on him, flog him and kill him. Three days later he will rise.” Mark 10.32-34
