Numbers 35:33

And He said, “What have you done? The voice of your brother’s blood is crying out to Me from the ground.

“Whoever sheds man’s blood, By man his blood shall be shed, For in the image of God He made man.

“But if he did not lie in wait for him, but God let him fall into his hand, then I will appoint you a place to which he may flee.

“Now this is the case of the manslayer who may flee there and live: when he strikes down his friend without premeditation, not hating him previously—

“So innocent blood will not be shed in the midst of your land which Yahweh your God gives you as an inheritance, and bloodguiltiness be on you.

‘Atone for Your people Israel whom You have redeemed, O Yahweh, and do not place the guilt of innocent blood in the midst of Your people Israel.’ And the bloodguiltiness shall be atoned for them.

“Speak to the sons of Israel, saying, ‘Designate the cities of refuge, of which I spoke to you by the hand of Moses,

These were the appointed cities for all the sons of Israel and for the sojourner who sojourns among them, that whoever strikes down any person unintentionally may flee there and not die by the hand of the avenger of blood until he stands before the congregation.

so that the violence done to the seventy sons of Jerubbaal might come, and their blood might be laid on Abimelech their brother, who killed them, and on the lords of Shechem, who strengthened his hands to kill his brothers.

And the king said to him, “Do as he has spoken and fall upon him and bury him, that you may remove from me and from my father’s house the blood which Joab shed without cause.

And they shed innocent blood, The blood of their sons and their daughters, Whom they sacrificed to the idols of Canaan; And the land was polluted with the blood.

The earth is also polluted by its inhabitants, for they trespassed laws, violated statutes, broke the everlasting covenant.

“I will first doubly repay their iniquity and their sin because they have profaned My land; they have filled My inheritance with the carcasses of their detestable idols and with their abominations.”

“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 Yahweh has sent me to you to speak all these words in your hearing.”
