And the book of jasher keeps delivering more

Laban, the father of Rachel and Leah, who tricks Jacob into a second 7 year of service by pretending to give Rachel but then giving Leah, because of custom, has a set of "images" - "and some make them in the figures of men, of gold and silver" and these images were imbued with the power of clairvoyance

It does not say they were graven, and the thing I get from this is they were icons

Rachel steals them from Laban so that Jacob can escape without Laban knowing to where...

"images" is the words in the text, not idols.
