'It is I' in the Bible

And mine eye shall not spare, neither will I have pity: I will render unto thee according to thy ways, and thine abominations shall be in the midst of thee; and ye shall know that it is I, Jehovah, that smite.

Therefore thus saith the Lord Jehovah unto them: Behold, it is I, and I will judge between the fat sheep and the lean sheep.
