Numbers 25:12

My covenant of peace That is, the covenant of an everlasting priesthood, as it is expounded Numbers 25:13, which is called a covenant of peace, partly with respect to the happy effect of this heroical action of his, whereby he made peace between God and his people, and partly with regard to the principal end of the priestly office, which was constantly to do that which Phinehas now did, even to mediate between God and men, in order to their peace and reconciliation with him, by offering up sacrifices and prayers to God on their behalf; as also by turning them away from iniquity, which is the only peace-breaker; and by teaching and pressing upon them the observation of that law, which is the only bond of their peace.
