'Treacherously' in the Bible

Have we not all one father? hath not one God created us? why do we deal treacherously every man against his brother, profaning the covenant of our fathers?

Judah hath dealt treacherously, and an abomination is committed in Israel and in Jerusalem; for Judah hath profaned the holiness of Jehovah which he loveth, and hath married the daughter of a foreign god.

Yet ye say, Wherefore? Because Jehovah hath been witness between thee and the wife of thy youth, against whom thou hast dealt treacherously, though she is thy companion, and the wife of thy covenant.

And did he not make one, although he had the residue of the Spirit? And wherefore one? He sought a godly seed. Therefore take heed to your spirit, and let none deal treacherously against the wife of his youth.

For I hate putting away, saith Jehovah, the God of Israel, and him that covereth his garment with violence, saith Jehovah of hosts: therefore take heed to your spirit, that ye deal not treacherously.
