'Unfaithfulness' in the Bible

Son of man, when a land sinneth against me by working unfaithfulness, and I stretch out my hand upon it, and break the staff of the bread thereof, and send famine upon it, and cut off man and beast from it;

And I will make the land a desolation, because they have wrought unfaithfulness, saith the Lord Jehovah.

And I will spread my net upon him, and he shall be taken in my snare; and I will bring him to Babylon, and will enter into judgment with him there for his unfaithfulness in which he hath been unfaithful against me.

And when the righteous turneth from his righteousness and practiseth what is wrong, and doeth according to all the abominations that the wicked doeth, shall he live? None of his righteous acts which he hath done shall be remembered: in his unfaithfulness which he hath wrought, and in his sin which he hath sinned, in them shall he die.

Therefore, son of man, speak unto the house of Israel, and say unto them, Thus saith the Lord Jehovah: In this moreover have your fathers blasphemed me, in that they have wrought unfaithfulness against me.

and they shall bear their confusion, and all their unfaithfulness in which they have acted unfaithfully against me, when they shall dwell safely in their land, and none shall make them afraid;
