'Blood' in the Bible

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

and Eleazar the priest shall take of her blood with his finger, and sprinkle her blood toward the front of the Tent of Meeting seven times.

One shall burn the heifer in his sight; her skin, and her flesh, and her blood, with her dung, shall he burn:

Behold, the people rises up as a lioness, As a lion he lifts himself up. He shall not lie down until he eat of the prey, and drinks the blood of the slain."

The avenger of blood shall himself put the murderer to death: when he meets him, he shall put him to death.

or in enmity struck him with his hand, so that he died; he who struck him shall surely be put to death; he is a murderer: the avenger of blood shall put the murderer to death, when he meets him.

then the congregation shall judge between the striker and the avenger of blood according to these ordinances;

and the congregation shall deliver the manslayer out of the hand of the avenger of blood, and the congregation shall restore him to his city of refuge, where he was fled: and he shall dwell therein until the death of the high priest, who was anointed with the holy oil.

and the avenger of blood find him outside of the border of his city of refuge, and the avenger of blood kill the manslayer; he shall not be guilty of blood,

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