Abideth (menei). Present active indicative, continues in the light and so does not interrupt the light by hating his brother. Occasion of stumbling (skandalon). See on Matthew 13:41 ; Matthew 16:23 for this interesting word. It is a stumbling block or trap either in the way of others (its usual sense), as in Matthew 18:7 , or in one's own way, as is true of proskoptw in John 11:9 and in verse 1 John 2:11 here. But, as Westcott argues, John may very well have the usual meaning here and the other in verse 1 John 11 .
