'Blood' in the Bible

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.

And 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 riseth up as a lioness, And as a lion doth he lift himself up: He shall not lie down until he eat of the prey, And drink the blood of the slain.

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

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

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, whither 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 without the border of his city of refuge, and the avenger of blood slay the manslayer; he shall not be guilty of blood,

So ye shall not pollute the land wherein ye are: for blood, it polluteth the land; and no expiation can be made for the land for the blood that is shed therein, but by the blood of him that shed it.
