Numbers 25:11, 13

“Phinehas son of Eleazar, the son of Aaron, the priest, has saved the Israelites from my anger. He hates sin as much as I do. Since he tried to save my honor among them, I will not kill them.

He and his descendants will always be priests, because he had great concern for the honor of his God. He removed the sins of the Israelites so they would belong to God.”
