'Blood' in the Bible

But you are not to redeem the firstborn of a cow, sheep, or a female goat. They are holy. You are to sprinkle their blood on the altar and burn their fat for an offering made by fire, a pleasing aroma to the LORD.

Then Eleazar the priest is to take blood from it with his finger and sprinkle the blood in front of the Tent of Meeting.

The entire heifer is to be incinerated in his presence, including its skin, its flesh, its blood, and its dung.

Look! The people are like lions. Like the lion, he rises up! He does not lie down again until he has consumed his prey and drunk the blood of the slain."

They are to serve as cities of refuge from a blood avenger in order to keep the inadvertent killer from dying until he has stood trial in the presence of the community.

The blood avenger himself is to execute the murderer. When he meets him, the blood avenger is to put him to death.

or if he struck him with his hand out of hatred so that he died, then the killer is certainly to be put to death for murder. The avenger of blood is to put him to death when he meets him."

then the community is to judge between the inadvertent killer and the blood avenger, following these ordinances.

The community is to release the inadvertent killer from the blood avenger and return him to the town of refuge where he had fled. He is to live there until the High Priest dies, who will have anointed him with holy oil.

and the blood avenger finds him outside the town of refuge where he had fled and kills him, the blood avenger is not to be found guilty of murder.

You are not to pollute the land where you live, because blood defiles the land, and the land cannot atone for blood that has been spilled on it, except through the blood of the one who spilled it.
