'Life' in the Bible

For the life of the flesh is in the blood; and I have given it to you upon the altar to make atonement for your souls: for it is the blood that maketh atonement by reason of the life.

For as to the life of all flesh, the blood thereof is all one with the life thereof: therefore I said unto the children of Israel, Ye shall eat the blood of no manner of flesh; for the life of all flesh is the blood thereof: whosoever eateth it shall be cut off.

And he that smiteth a beast mortally shall make it good, life for life.
