'Unleavened' in the Bible

And Gideon hath gone in, and prepareth a kid of the goats, and of an ephah of flour unleavened things; the flesh he hath put in a basket, and the broth he hath put in a pot, and he bringeth out unto Him, unto the place of the oak, and bringeth it nigh.

And the messenger of God saith unto him, 'Take the flesh and the unleavened things, and place on this rock -- and the broth pour out;' and he doth so.

And the messenger of Jehovah putteth forth the end of the staff which is in His hand, and cometh against the flesh, and against the unleavened things, and the fire goeth up out of the rock and consumeth the flesh and the unleavened things -- and the messenger of Jehovah hath gone from his eyes.
