Make us gods to go before us
Stephen repeats Israel's demand that Aaron make gods to go before them and recounts the calf, its sacrifice, and the people's rejoicing in what their hands had made.
But our fathers refused to obey him. Instead, they rejected him and in their hearts turned back to Egypt. They said to Aaron, ‘Make us gods who will go before us! As for this Moses who led us out of the land of Egypt, we do not know what has happened to him.’ At that time they made a calf and offered a sacrifice to the idol, rejoicing in the works of their hands.
Exodus 32:1-4 records the demand, the collected gold, and the fashioned calf; Acts 7:39-41 quotes the demand and describes the calf, sacrifice, and celebration.
