'Accident' in the Bible

When there is in thee a man who is not clean, from an accident at night -- then he hath gone out unto the outside of the camp -- he doth not come in unto the midst of the camp --

and ye have seen, if the way of its own border it goeth up to Beth-Shemesh -- He hath done to us this great evil; and if not, then we have known that His hand hath not come against us; an accident it hath been to us.'

And Saul hath not spoken anything on that day, for he said, 'It is an accident; he is not clean -- surely not clean.'
