In the Bible I use for my Lit Hum class, I also have found an interesting typographical error. It is the Meridian printing, which belongs to the Penguin Publishing group, of the RSV of Gen. 4:7. The story is of Cain and Abel. Abel's sacrifice to the LORD was accepted and Cain's was not. Cain becomes angry in response, but the LORD speaks to Cain, saying (with the typo included):
Why are you angry, and why has your countenance fallen? If you do well, will you not be accepted? And if you do not do well, sin is couching at the door; its desire is for you, but you must master it.
With the typo, it seems that sin is spending the night, perhaps even bedding down at the door. The language of "couching" adjacent to "desire" is suggestive of sexual attraction being applied to sin. It is trying to tempt you into bed. But, this is a typo. The real version is "crouching" and not "couching." This suggests a different set of images. Instead of sexually seductive, it is a menacing animal. Crouching is like a beast poised in the position to spring and to strike. Instead of sexual desire, it is seeking to devour. You are its food. Instead of mastering a seducer, you are to tame this lion. It is a powerful image, but one lost in this edition by this modern scribal error, and, with mass printing, it is a widely disseminated error.
