'Calf shaped' in the Bible

Only Jehu did not turn aside from the sins of Jeroboam the son of Nebat [by] which he caused Israel to sin; [namely,] the calf-shaped idols of gold which [were in] Bethel and Dan.

They abandoned all the commands of Yahweh their God and made for themselves two molten calf-shaped idols; they made a pole of Asherah worship and bowed down to the army of the heavens and served Baal.
