John Calvin Commentary Ezekiel 9:10

"And as for me also, mine eye shall not spare, neither will I have pity, but I will bring their way upon their head." — Ezekiel 9:10 (ASV)

Now God pronounces the Jews to be so obstinate in their malice that they have cut off from themselves all hope of pardon. For when he now says, that he would be hostile to them without pity, he shows the necessity of taking vengeance, because their impiety had penetrated even heaven, so that he could not spare them without denying himself.

And abrupt speech increases vehemence, as if God pronounced that he had changed his plans. So now we understand the meaning of this answer: the Jews were bound by so many and such impious crimes that they had closed the door of God’s pity. Indeed, they had compelled him to the utmost degree of vengeance, because they continued to provoke him more and more.

Let us then learn from this passage not to weigh God’s judgments in our scale, because we are too much accustomed to extenuate our sins and to treat our serious iniquities as slight errors, because we do not attribute just honor to God as the only judge.

Now, when God commands his Prophet to rest and be silent, he undoubtedly at the same time restrains our rashness, through which we burst forth in disobedience when he seems too rigid to us.

But, as I have said, we do not consider the greatness of our sins. Therefore, it is God’s province alone to pronounce on sins, so that no mortal should presume to estimate the quality of actions, for then we encroach upon God’s unique role.
