Genesis 4:8-12 (NIV)
Now Cain said to his brother Abel, “Let’s go out to the field.” And while they were in the field, Cain attacked his brother Abel and killed him. Then the LORD said to Cain, “Where is your brother Abel?” “I don’t know,” he replied. “Am I my brother’s keeper?” The LORD said, “What have you done? Listen! Your brother’s blood cries out to me from the ground. Now you are under a curse and driven from the ground, which opened its mouth to receive your brother’s blood from your hand. When you work the ground, it will no longer yield its crops for you. You will be a restless wanderer on the earth.”

Matthew 27:3-5 (NIV)
When Judas, who had betrayed him, saw that Jesus was condemned, he was seized with remorse and returned the thirty silver coins to the chief priests and the elders. “I have sinned,” he said, “for I have betrayed innocent blood.” “What is that to us?” they replied. “That’s your responsibility.” So Judas threw the money into the temple and left. Then he went away and hanged himself.

Matthew 27:24-26 (NIV)
When Pilate saw that he was getting nowhere, but that instead an uproar was starting, he took water and washed his hands in front of the crowd. “I am innocent of this man’s blood,” he said. “It is your responsibility!” All the people answered, “Let his blood be on us and on our children!” Then he released Barabbas to them. But he had Jesus flogged, and handed him over to be crucified.

Matthew 27:41-43 (NIV)
In the same way the chief priests, the teachers of the law and the elders mocked him. “He saved others,” they said, “but he can’t save himself! He’s the King of Israel! Let him come down now from the cross, and we will believe in him. He trusts in God. Let God rescue him now if he wants him, for he said, `I am the Son of God.'”
