Exodus 32:28-30

Amplified Bible, Classic Edition

²⁸ And the sons of Levi did according to the word of Moses; and there fell of the people that day about 3000 men.

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.
