'Blood' in the Bible

But the firstborn of an ox or the firstborn of a sheep or the firstborn of a goat, you shall not redeem; they are holy. You shall sprinkle their blood on the altar and shall offer up their fat in smoke as an offering by fire, for a soothing aroma to the Lord.

Next Eleazar the priest shall take some of its blood with his finger and sprinkle some of its blood toward the front of the tent of meeting seven times.

Then the heifer shall be burned in his sight; its hide and its flesh and its blood, with its refuse, shall be burned.

“Behold, a people rises like a lioness,And as a lion it lifts itself;It will not lie down until it devours the prey,And drinks the blood of the slain.”

The blood avenger himself shall put the murderer to death; he shall put him to death when he meets him.

or if he struck him down with his hand in enmity, and as a result he died, the one who struck him shall surely be put to death, he is a murderer; the blood avenger shall put the murderer to death when he meets him.

then the congregation shall judge between the slayer and the blood avenger according to these ordinances.

The congregation shall deliver the manslayer from the hand of the blood avenger, and the congregation shall restore him to his city of refuge to which he fled; and he shall live in it until the death of the high priest who was anointed with the holy oil.

and the blood avenger finds him outside the border of his city of refuge, and the blood avenger kills the manslayer, he will not be guilty of blood

So you shall not pollute the land in which you are; for blood pollutes the land and no expiation can be made for the land for the blood that is shed on it, except by the blood of him who shed it.
