'Harness' in the Bible

And the king of Israel answered and said, Tell him, Let not him that girdeth on his harness boast himself as he that putteth it off.

And a certain man drew a bow at a venture, and smote the king of Israel between the joints of the harness: wherefore he said unto the driver of his chariot, Turn thine hand, and carry me out of the host; for I am wounded.
