'Treacherously' in the Bible

"Surely as a wife treacherously departs from her husband, so you have dealt treacherously with me, house of Israel," says Yahweh.

For the house of Israel and the house of Judah have dealt very treacherously against me," says Yahweh.

You are righteous, Yahweh, when I contend with you; yet I would reason the cause with you: why does the way of the wicked prosper? why are all they at ease who deal very treacherously?

For even your brothers, and the house of your father, even they have dealt treacherously with you; even they have cried aloud after you: don't believe them, though they speak beautiful words to you.
