'It is I' in the Bible

Yet he does not plan this, nor does his heart think so. For it is in his heart to destroy and cut off not a few nations.

For so it is in the midst of the land among the people, it shall be like the shaking of an olive tree and as gleanings when the grape harvest is completed.

Therefore My people shall know My name; So it shall be in that day, for I am He who speaks; behold, it is I.
