   In Mark 9:47 and Matthew 18:9, the accusative singular masculine form occurs after the instruction to cast out or remove an eye that causes stumbling. In Mark 9:47 the APB renders the contrast as entering “the kingdom of God one-eyed” rather than being thrown into Gehenna with two eyes; Matthew 18:9 similarly renders entering life “one-eyed.”

   Mark 9:47Matthew 18:9

In the Anselm Project Bible: Across both verses, the APB presents the condition with “one-eyed,” set against having “two eyes.” This reflects the clause-level presentation rather than a separate lexical definition.
