Exodus 32:4-6

Thomson(i) 4 and he received them at their hands and having made of them a molten bull he fashioned it with a graving tool and said, These are thy gods Israel, who brought thee up out of the land of Egypt. 5 And when Aaron saw it he built an altar before it. And Aaron made proclamation, saying, To-morrow is the festival of the Lord. 6 So rising early in the morning he caused whole burnt offerings to be brought up, and offered a sacrifice of thanksgiving; and the people sat down to eat and drink and rose up to play.
