Crack open a copy of the so-called Wicked Bible to Exodus 20, and you’ll find a pretty standard version of the 10 Commandments, albeit with 17th-century spelling twists: “Honour thy father and thy mother, that thy dayes may bee long upon the land which the LORD thy God giveth thee. Thou shalt not kill.”

And then you hit verse 14: “Thou shalt commit adultery.”

Yeah, oops. That missing “not” is kind of important.

One of history’s most titillating biblical misprints is back in the news: A copy, said to be one of about 10 left, is going on auction at Bonhams in the United Kingdom. Once the error was discovered, about a year after roughly 1,000 of the books were printed in 1631, most copies were burned, which is why they’re so rare. The printers, Robert Barker and Martin Lucas, were brought to court and fined by King Charles I of England, and they lost their printing licenses. Barker later died in debtor’s prison.

And: There’s intrigue! As if a biblical endorsement of hanky-panky weren’t enough. There’s a rumor that another printer purposefully inserted the error, said Diana Severance, the director of the Dunham Bible Museum in Houston, Texas, which also has a copy of the book. The strongest evidence? “There is another error,” she said. In “Deuteronomy 5:24, when it talks about the ‘greatness’ of God, it has ‘great-asse.’” The 10 Commandments appear only twice in the Bible: once in Deuteronomy 5, and again in Exodus 20, the very two places where the Wicked Bible contains errors. One could understand a dropped “not,” maybe, but “‘great-asse’ is not a typical typographical error,” Severance said. “It’s not just an accidental mistake.”
