Phinehas, the son of Eleazar, the son of Aaron, hath turned away from the children of Israel, while he was zealous for my sake among them that I consumed not the children of Israel in my jealousy.

Wherefore say, Behold, I give unto him my covenant of peace:

And he shall have it, and his seed after him, even the covenant of an everlasting priesthood;

because he was zealous for his God …. Numbers 25: 11, 12, 13
