Not firsthand, but my great-great-grandfather was reportedly an awful human being, and the story goes that when my great-grandfather got religion, got married and moved away, his father tracked him down, dragged him home, horsewhipped him and left him tied to a post rather than give up a free fieldhand. His mother had to wait till dark, then soak him in a tub of hot water to remove the shredded clothes that his blood had dried into his wounds.
That's nothing like what Peterson did; Peterson definitely went too far, and should have waited till he cooled down enough he WOULDN'T, but calling it a beating is sensationalized exaggeration.
No, it's not: The biblically inspired verbatim phrase is from an English poem that predates de Sade by a century:

It orginates in Proverbs 3:11,12 and 13:24, and Paul quotes and elaborates on the former in Hebrews 12; that, and the reverence most East Texas jurors pay the bible, is why I previously quoted those sections. Good luck convincing a dozen East Texans to unanimously agree Adrian Peterson should go to prison for doing what the bible says. Again, it took TWO grand juries just to INDICT him.
