'Fields' in the Bible

And the king commandeth Hilkiah the high priest, and the priests of the second order, and the keepers of the threshold, to bring out from the temple of Jehovah all the vessels that are made for Baal, and for the shrine, and for all the host of the heavens, and he burneth them at the outside of Jerusalem, in the fields of Kidron, and hath borne their ashes to Beth-El.
