'It is I' in the Bible

For the soul of the flesh it is in the blood; and I gave it to you upon the altar to expiate for your souls: for the blood shall expiate for the soul.

For the soul of all flesh it is its blood in its soul: and say to the sons of Israel, The blood of all flesh ye shall not eat, for the soul of all flesh it is its blood: all eating it shall be cut off.
