DEU 23:14

14 For thy Lord God goeth in (the) midst of the tents, that he deliver thee, and betake thine enemies to thee, that thy tents be holy, and nothing of filth appear in them, lest for uncleanness he forsake thee. (For the Lord thy God goeth in the midst of thy tents, to keep thee safe, and to deliver thy enemies to thee, so thy tents must be kept holy, and nothing of filth appear in them, otherwise he shall leave thee because of thy uncleanness.)
