Numbers 25:12 - Matthew Poole's English Annotations on the Holy Bible

i.e. 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 and use of the priestly office, which was constantly to do that which Phinehas now did, even to mediate between God and men, to obtain and preserve his own and Israel's peace and reconciliation with God, by offering up sacrifices, and incense, and prayers to God on their behalf, Numbers 16:47,48, as also by turning them away from iniquity, which is the only peace-breaker, and by teaching and pressing the observation of that law, which is the only bond of their peace, Zechariah 2:5-7.
