'Unfaithfulness' in the Bible

“Lift up your eyes to the barren heights and see;Where have you not been violated?You sat by the road waiting [eagerly] for them [those man-made gods]Like an Arab [tribesman who waits to attack] in the desert,And you have desecrated the landWith your [vile] prostitution and your wickedness (disobedience to God).

Return, you faithless children.I will heal your unfaithfulness.“Here we are, coming to You,for You are the Lord our God.
