2 Bible Verses about Calf worship

"And they made a calf in those days, and offered a sacrifice to this idol, and began to rejoice over what they had made with their hands.

For although they knew God, yet they did not glorify him as God, nor give him thanks; but became vain in their reasoning, and their senseless minds were darkened. While they professed to be wise, they became fools, and exchanged the majesty of the imperishable God for an idol, graven in the likeness of perishable man, or of birds and four-footed beasts and creeping things.
