'I Am He' in the Bible

Heal me, O Jehovah, and I am healed, Save me, and I am saved, for my praise art Thou.

Because that they have done folly in Israel, and commit adultery with the wives of their neighbours, and speak a word in My name falsely that I have not commanded them, and I am He who knoweth and a witness -- an affirmation of Jehovah.
