'Innocent Blood' in the Bible

if you do not oppress the alien, the orphan, or the widow, and do not shed innocent blood in this place, nor walk after other gods to your own ruin,

Thus says the Lord, “Do justice and righteousness, and deliver the one who has been robbed from the power of his oppressor. Also do not mistreat or do violence to the stranger, the orphan, or the widow; and do not shed innocent blood in this place.

“But your eyes and your heartAre intent only upon your own dishonest gain,And on shedding innocent bloodAnd on practicing oppression and extortion.”

Only 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 truly the Lord has sent me to you to speak all these words in your hearing.”
