Numbers 16:49

even those men who brought out the very bad report of the land died by a plague before Yahweh.

So those who died by the plague were 24,000.

Then Araunah said, “Why has my lord the king come to his servant?” And David said, “To buy the threshing floor from you, in order to build an altar to Yahweh, that the plague may be checked from being upon the people.”

Before Him goes pestilence, And plague comes after Him.

Nor grumble, as some of them did, and were destroyed by the destroyer.
