Exodus 32:28-30

Revised Geneva Translation

²⁸ So, the children of Levi did as Moses had commanded. And about three thousand men of the people fell that day.

²⁹ For Moses had said, “Every man consecrate yourself to the LORD this day— even against your son, and against your brother — so that a blessing may be given to you this day.”

³⁰ And when the morning came, Moses said to the people, “You have committed a grievous crime. But now I will go up to the LORD, to see if I may pacify Him for your sin.”
