2 Bible Verses about Calf worship

And they made a calf in those days, and offered a sacrifice to the idol, and rejoiced in the works of their hands.

because having known God they glorified him not as God neither were thankful, but became vain in their reasonings and their ignorant mind was darkened. Saying that they were wise they became foolish, and changed the glory of the imperishable God into the likeness of the image of perishable man, and of birds, and quadrupeds, and reptiles.
