'Treacherously' in the Bible

“Surely, as a wife treacherously (unfaithfully) leaves her husband,So you have dealt treacherously with Me,O house of Israel,” says the Lord.

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

“What right has My beloved [to be] in My houseWhen she has done many vile things and acted treacherously [over and over again]?Can vows and the meat of your sacrifices remove your wickedness from you and cancel the consequences of your sin,So that you can [escape your judgment and] rejoice?”

You, O Lord are [uncompromisingly] righteous and consistently just when I plead my case with You;Yet let me discuss issues of justice with You:Why has the way of the wicked prospered?Why are those who deal in treachery (deceit) at ease and thriving?

“For even your [tribal] brothers and the household of your father,Even they have dealt treacherously (unfaithfully) with you;Indeed they are [like a pack of hounds] howling after you.Do not believe them, although they may say kind words and promise you good things.”
