'No gods' in the Bible

Has a nation changed its gods, which are yet no gods? but my people have changed their glory for that which does not profit.

How shall I pardon you for this? your children have forsaken me, and sworn by them that are no gods: when I had fed them to the full, they then committed adultery, and assembled themselves by troops in the harlots' houses.

Shall a man make gods unto himself, and they are no gods?
