'Disloyal' in the Bible

Judah has become disloyal, and unspeakable sins have been committed in Israel and Jerusalem. For Judah has profaned the holy things that the Lord loves and has turned to a foreign god!

No one who has even a small portion of the Spirit in him does this. What did our ancestor do when seeking a child from God? Be attentive, then, to your own spirit, for one should not be disloyal to the wife he took in his youth.
