TSK · Deuteronomy 21:8

“You must not pollute the land where you live, for blood defiles the land, and the land cannot be cleansed of the blood that is shed there, except by the blood of the person who shed it.

Because he killed innocent people and stained Jerusalem with their blood, the LORD was unwilling to forgive them.

But you should take careful note of this: If you put me to death, you will bring on yourselves and this city and those who live in it the guilt of murdering an innocent man. For the LORD has sent me to speak all this where you can hear it. That is the truth!”

They will attack you with weapons, chariots, wagons, and with a huge army; they will array themselves against you on every side with large shields, small shields, and helmets. I will assign them the task of judgment; they will punish you according to their laws.

so that on you will come all the righteous blood shed on earth, from the blood of righteous Abel to the blood of Zechariah son of Barachiah, whom you murdered between the temple and the altar.
