Charles H. Spurgeon on Psalms 106:30

So the plague was stayed. God himself puts this peculiar honour of staying the plague (when he was about to destroy the whole camp) upon this fact of Phinehas, saying, "He hath turned away my wrath", Nu 25:10-11, because he was acted with the same zeal for God's glory and Israel's good, as God himself is acted with for them, and feared not to lose his life in God's cause, by putting to death a prince and a princess in the very flagrancy of their lust at one blow. There is such an accent and such an emphasis put by the Lord on this act, (as the Jewish Rabbis observe), that here they begin the forty-first section or lecture of the Law, or (as Vatablus saith) the seventh section of the book, which they call Phinehas. Moreover, it teacheth us, that zeal of justice in the cause of God is an hopeful means to remove God's wrath from, and to procure his mercy to, man. Thus David also made an atonement by doing justice on Saul's house, 2Sa 21:3, etc. . . . Phinehas by virtue of this promise of the priesthood (Nu 25:12-13) lived himself to a great old age, even (as some say) to three hundred years, as appeareth by Jud 20:28, where he then is found alive, for his zeal at this time. He lived so long that some of the Rabbis are of opinion that he died not at all, but is still alive, whom they suppose to be the Elias that is to come before the coming of Christ; but this notion is confuted by others of their Rabbis, and by the mention of his seed succeeding him in sacred Scripture. However, though few after the Flood did near attain to any such age, yet must Phinehas be very old in that time of Israel's warring with Benjamin...Phinehas's priesthood is called "everlasting", not in his person, but in his posterity, whose sons were successively high priests till the captivity of Babylon, 1Ch 6:4-16; and at the return out of captivity, Ezra, the great priest and scribe, was of his line, Ezr 7:1-6; and so it continued in that line until, or very near, the approach of our evangelical High Priest (as Christ is called, Heb 5:6), who was of the order of Melchizedek.
