'Innocent Blood' in the Bible

if you do not oppress the transient and the foreigner, the orphan, or the widow, and do not shed innocent blood [by oppression and by unjust judicial murders] in Jerusalem, nor follow after other gods to your own ruin,

Thus says the Lord, “Execute justice and righteousness, and rescue the one who has been robbed from the hand of his oppressor. And do no wrong; do no violence to the stranger, the fatherless, or the widow, nor shed innocent blood in this place.

“But your eyes and your heartAre only intent on your own dishonest gain,On shedding innocent blood,On oppression and extortion and violence.”

But know for certain that if you put me to death, you will bring innocent blood on yourselves and on this city and on its inhabitants, for in truth the Lord has sent me to you to speak all these words in your hearing.”
