Genesis 9:5

And Reuben answered them, saying, “Did I not tell you, saying, ‘Do not sin against the boy’; yet you would not listen? So also his blood, behold, it is required of us.”

“And if an ox gores a man or a woman to death, the ox shall surely be stoned and its flesh shall not be eaten; but the owner of the ox shall go unpunished.

Thus God returned the evil of Abimelech, which he had done to his father in killing his seventy brothers.

“How much more, when wicked men have killed a righteous man in his own house on his bed, shall I not now require his blood from your hand and purge you from the earth?”

Thus Joash the king did not remember the lovingkindness which his father Jehoiada had shown him, but he killed his son. And as he died he said, “May Yahweh see and avenge!”

For He who requires blood remembers them; He does not forget the cry of the afflicted.
