Therefore say, ‘Behold, I give to Phinehas my covenant of peace, and it shall be to him and to his descendants after him the covenant of a perpetual priesthood, because he was jealous for his God and made atonement for the people of Israel.’
Numbers 25:12-13

The Aaronic Priesthood, including at least the descendants of Phinehas, will stand as long as heaven and earth. See also Matthew 5:18. #pinchas
