'Innocent Blood' in the Bible

so that innocent blood may not be shed in your land which Jehovah your God gives you for an inheritance, and blood may not be on you.

Your eye shall not pity him, but you shall put away innocent blood from Israel, so that it may go well with you.

Be merciful, O Jehovah, to Your people Israel, whom You have redeemed, and do not lay innocent blood to the charge of Your people Israel. And the blood shall be forgiven them.

So you shall put away innocent blood from among you, when you do the right in the sight of Jehovah.
