'Treacherously' in the Bible

However, as a wife departs treacherously from her lover, so you have dealt treacherously with me, house of Israel," {declares} Yahweh.

For the house of Israel and the house of Judah have dealt utterly treacherously with me," {declares} Yahweh.

You [will be] in the right, Yahweh, when I complain to you. Even so, let me speak [my] claims with you. Why does [the] way of [the] wicked succeed? All those who deal treacherously with treachery are at ease.

For even your relatives, and the house of your father, even they have dealt treacherously with you, even they call {loudly} after you. You must not trust in them, though they speak kindly to you.
