Exodus 32:29-31

Amplified Bible

²⁹ Then Moses said [to the Levites], “Dedicate yourselves today to the Lord—for each man has been against his own son and his own brother [in his attempt to escape execution]—so that He may restore and bestow His blessing on you this day.”

³⁰ Then the next day Moses said to the people, “You have committed a great sin. Now I will go up to the Lord; perhaps I can make atonement for your sin.” ³¹ So Moses returned to the Lord, and said, “Oh, these people have committed a great sin [against You], and have made themselves a god of gold.
