'Treacherously' in the Bible

Surely as a woman treacherously departeth from her companion, so have ye dealt treacherously with me, O house of Israel, saith Jehovah.

For the house of Israel and the house of Judah have dealt very treacherously against me, saith Jehovah.

Righteous art thou, Jehovah, when I plead with thee; yet will I speak with thee of thy judgments. Wherefore doth the way of the wicked prosper? wherefore are all they at ease that deal very treacherously?

For even thy brethren, and the house of thy father, even they have dealt treacherously with thee, even they have cried aloud after thee. Believe them not, though they speak good words unto thee.
