'Adulterers' in the Bible

Who doth give me in a wilderness A lodging-place of travellers? And I leave my people, and go from them, For all of them are adulterers, An assembly of treacherous ones.

For of adulterers hath the land been full, For because of these hath the land mourned, Dried up hath been the pleasant places of the wilderness, And their course is evil, and their might -- not right.
