'Treacherously' in the Bible

“Surely, as a woman treacherously departs from her lover,So you have dealt treacherously with Me,O house of Israel,” declares the Lord.

“For the house of Israel and the house of JudahHave dealt very treacherously with Me,” declares the Lord.

“For even your brothers and the household of your father,Even they have dealt treacherously with you,Even they have cried aloud after you.Do not believe them, although they may say nice things to you.”
