Exodus 32:4-6

Wycliffe Bible

⁴ and when he had taken those, he formed them by work of melting, and he made of them a molten calf (and he made a calf out of the melted gold). And they said, Israel, these be thy gods, that led thee out of the land of Egypt.

⁵ And when Aaron had seen this thing, he builded an altar before the calf, and he cried by the voice of a crier, and said, Tomorrow is the solemnity of the Lord. (And when Aaron had seen this thing, he built an altar before the calf, and he cried by the voice of a crier, and said, Tomorrow shall be a Feast to the Lord.)

⁶ And they rose (up) early, and offered burnt sacrifices, and peaceable sacrifices (and peace offerings); and the people sat (down) to eat and to drink, and (then) they rose up to play, or to scorn, for idolatry is (the) scorning of God.
