TSK · Numbers 25:9

And the LORD sent a plague on the people because they had made the calf– the one Aaron made.

Now 14,700 people died in the plague, in addition to those who died in the event with Korah.

A Second Census Required After the plague the LORD said to Moses and to Eleazar son of Aaron the priest,

You have witnessed what the LORD did at Baal Peor, how he eradicated from your midst everyone who followed Baal Peor.

And let us not be immoral, as some of them were, and twenty-three thousand died in a single day.
