Numbers 25:15-19

And the name of the Midianite woman who was killed was Cozbi the daughter of Zur, who was head of the people of a father’s household in Midian.

Then the Lord spoke to Moses, saying,

“Be hostile to the Midianites and attack them;

for they have been hostile to you with their tricks, with which they have deceived you in the matter of Peor and in the matter of Cozbi, the daughter of the leader of Midian, their sister who was killed on the day of the plague because of Peor.”
