'Fourth' in the Bible

Now it came to pass in the thirtieth year, in the fourth month, on the fifth of the month, as I was among the captives by the river Chebar, the heavens were opened, and I saw visions of God.

And every one had four faces: the first face was the face of a cherub, and the second face the face of a man, and the third the face of a lion, and the fourth the face of an eagle.
