This compound verb specifically describes the act of making a calf idol. In Acts 7:41, Stephen recounts Israel's apostasy at Sinai—they made a calf and offered sacrifice to the idol. The multilingual glosses identify calf-making (Spanish hicieron becerro, French faire un veau). The term is crafted precisely for this notorious incident, combining 'calf' with 'make.' Stephen's speech emphasizes that while Moses received living oracles on the mountain, the people below fashioned a dead idol, rejecting God for Egyptian-style idolatry.
