'Shed Blood' in the Bible

You will destroy the family of your master Ahab. I will get revenge against Jezebel for the shed blood of my servants the prophets and for the shed blood of all the Lord's servants.

"Know for sure that I saw the shed blood of Naboth and his sons yesterday," says the Lord, "and that I will give you what you deserve right here in this plot of land," says the Lord.' So now pick him up and throw him into this plot of land, just as the Lord said."
