Exodus 32:29-31

Amplified Bible, Classic Edition

²⁹ And Moses said [to the Levites, By your obedience to God’s command] you have consecrated yourselves today [as priests] to the Lord, each man [at the cost of being] against his own son and his own brother, that the Lord may restore and bestow His blessing upon you this day.

³⁰ The next day Moses said to the people, You have sinned a great sin. And 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 sinned a great sin and have made themselves gods of gold!
