But the highest reward to Phinehas was that God granted him everlasting priesthood. For Phinehas is none other than the prophet of Elijah. His task it is to make atonement for Israel, and without tasting of death, he constantly discharges the duties of his everlasting priesthood until the resurrection of the dead, offering up daily two sacrifices for the children of Israel, and upon the skins of these animals recording the events of each day. God furthermore said to Phinehas: "Thou hast in this world established peace between Me and Israel; in the future world also shalt thou establish peace between Me and them." He was therefore destined to be the forerunner of the Messiah to establish before his coming peace on earth.
