2 Bible Verses about Calf worship

"Moreover they made a calf at that time, and offered a sacrifice to the idol and kept rejoicing in the gods which their own hands had made.

For when they had come to know God, they did not give Him glory as God nor render Him thanks, but they became absorbed in useless discussions, and their senseless minds were darkened. While boasting of their wisdom they became utter fools, and, instead of worshipping the imperishable God, they worshipped images resembling perishable man or resembling birds or beasts or reptiles.
