2 Bible Verses about Calf worship

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

because, knowing God, they did not glorify Him as God, neither were they thankful; but they became vain in their reasonings, and their foolish heart was darkened. Saying that they were wise, they became fools, and changed the glory of the invisible God into the similitude of the likeness of corruptible man, and of birds, and of quadrupeds, and of creeping things.
