Clement of Alexandria

Correction is a public rebuke of sin. [God] uses it in a manner that is particularly necessary for our instruction because of the weak faith of so many. For example, he says through Isaiah, "You have forsaken the Lord, you have provoked the holy one of Israel."

Excoriation is the most vigorous expression of disapproval. God employed excoriation as a remedy when he said through Isaiah, "Ah, sinful nation, a people full of sins, an evil seed, lawless children."
