Exodus 32:4-6

Amplified Bible, Classic Edition

⁴ And he received the gold at their hand and fashioned it with a graving tool and made it a molten calf; and they said, These are your gods, O Israel, which brought you up out of the land of Egypt!

⁵ And when Aaron saw the molten calf, he built an altar before it; and Aaron made proclamation, and said, Tomorrow shall be a feast to the Lord.

⁶ And they rose up early the next day and offered burnt offerings and brought peace offerings; and the people sat down to eat and drink and rose up to play.
