Micah

masc. proper name, also the name of an archangel, from Late Latin Michael (source of French Michel, Spanish Miguel), from Greek Mikhael, from Hebrew Mikha-el, literally "Who is like God?" The modern form of the name was a learned form in Middle English, where the common form was Michel (also Mihhal, Mighel, etc.), from Old French. The surname Mitchell might be from the old pronunciation of Michael or in some cases it might be from Old English mycel "big."

1530s, a form of Hebrew Yah, short for Yahweh "Jehovah" (see Yahweh; also see J). Used in some English bibles. Cognate with the second element in hallelujah and in Elijah.
