'Blood' in the Bible

But you must not redeem the firstborn of a cow or a sheep or a goat; they are holy. You must splash their blood on the altar and burn their fat for an offering made by fire for a pleasing aroma to the Lord.

Eleazar the priest is to take some of its blood with his finger, and sprinkle some of the blood seven times directly in front of the tent of meeting.

Then the heifer must be burned in his sight -- its skin, its flesh, its blood, and its offal is to be burned.

Indeed, the people will rise up like a lioness, and like a lion raises himself up; they will not lie down until they eat their prey, and drink the blood of the slain."

The avenger of blood himself must kill the murderer; when he meets him, he must kill him.

or with enmity he strikes him with his hand and he dies, the one who struck him must surely be put to death, for he is a murderer. The avenger of blood must kill the murderer when he meets him.

then the community must judge between the slayer and the avenger of blood according to these decisions.

The community must deliver the slayer out of the hand of the avenger of blood, and the community must restore him to the town of refuge to which he fled, and he must live there until the death of the high priest, who was anointed with the consecrated oil.

and the avenger of blood finds him outside the borders of the town of refuge, and the avenger of blood kills the slayer, he will not be guilty of blood,

"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.
