Exodus 32:28-30

World English Bible

²⁸ The sons of Levi did according to the word of Moses. About three thousand men fell of the people that day. ²⁹ Moses said, “Consecrate yourselves today to Yahweh, for every man was against his son and against his brother, that he may give you a blessing today.”

³⁰ On the next day, Moses said to the people, “You have sinned a great sin. Now I will go up to Yahweh. Perhaps I shall make atonement for your sin.”
