'Idols' in the Bible

Ephraim is joined to idols: leave him alone.

They have set up kings, but not by me; they have made princes, and I knew it not; of their silver and their gold have they made them idols, that they may be cut off.

And now they sin more and more, and have made them molten images of their silver, idols according to their own understanding, all of it the work of the craftsmen: they say of them, Let the men that sacrifice kiss the calves.

Ephraim shall say, What have I to do any more with idols? (I answer him, and I will observe him.) I am like a green fir-tree. From me is thy fruit found.
