'Treacherously' in the Bible

But -- a woman hath deceived her friend, So ye have dealt treacherously with Me, O house of Israel, an affirmation of Jehovah.

For dealt treacherously against Me have the house of Israel, And the house of Judah, an affirmation of Jehovah.

For even thy brethren and the house of thy father, Even they dealt treacherously against thee, Even they -- they called after thee fully, Trust not in them, when they speak to thee good things.
