Exodus 32:29-31

Darby Translation

²⁹ And Moses said, Consecrate yourselves to-day to Jehovah, yea, every man with his son, and with his brother, and bring on yourselves a blessing to-day.

³⁰ And it came to pass the next day, that Moses said to the people, Ye have sinned a great sin. And now I will go up to Jehovah: perhaps I shall make atonement for your sin.

³¹ And Moses returned to Jehovah, and said, Alas, this people has sinned a great sin, and they have made themselves a god of gold!
