'Idols' in the Bible

Ephraim is joined to idols; let 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, even idols according to their own understanding, all of them 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 have answered, and will regard him: I am like a green fir-tree; from me is thy fruit found.
